    2012-01-01

    Lange engaged with Keynes in the matter of Keynes's macroeconomics, and over econometrics. Lange's interpretation of the Keynesian macroeconomic model laid the foundation for the neo-classical synthesis. But it was limited in its monetary economics. Lange also intervened in the Keynes-Tinbergen dispute over the scope and significance of econometrics. Lange collaborated in a paper that conceded Keynes's main point that empirical investigation could not determine theory, but insisted that theor...

  6. Gravity currents at Ormen Lange

    Energy Technology Data Exchange (ETDEWEB)

    Vikeboe, Frode; Berntsen, Jarle; Furnes, Gunnar

    2001-12-01

    Time series of temperature and velocities at Ormen Lange, located in the Storegga region off mid-Norway, indicate that close to the seabed, at depths ranging from 500-1000 m, large temperature fluctuations are accompanied by short peak values in speed. The extreme events are driven by strong pressure gradients, due to strong atmospheric low pressures and/or internal pressure fronts between warmer Atlantic Water (AW) and colder Norwegian Sea Water (NSW). Along the shelf slope at OL we may get steepening of the iso surfaces of density, separating AW and NSW, due to strong Ekman veering during storms or approaching internal density fronts. During such events the density surfaces tend to undershoot their equilibrium level, and as the forcing weakens, the suppressed water may run up along the shelf slope. In this run up phase, peak values in the velocities are often found. As a result of the run up phase, heavy water may be elevated onto the shelf. Subsequently dense fluid will spread under the influence of forces produced by its own buoyancy and motions of this form are often referred to as gravity currents. They are characterised by the distinctive nature of the front, which consists of a raised head leading a shallower flow behind. The shape of the head and body of the gravity current, along with velocity, depend on a range of parameters. This report investigates the velocities that may occur with parameters of relevance for Ormen Lange. (author)

    Cornelia de Lange syndrome is a rare genetic disease characterized by distinctive facial dysmorphia and dwarfism. Multiple organ system involvement is typical. Various central nervous system (CNS) aberrations have been described in the pathology literature; however, the spectrum of neuroimaging manifestations is less well documented. To present neuroimaging findings from a series of eight patients with Cornelia de Lange syndrome. The CT/MR database at a single academic children's hospital was searched for the terms ''Cornelia'', ''Brachmann'' and ''de Lange.'' The search yielded 18 exams from 16 patients. Two non-CNS and six exams without available images were excluded. Ten exams from eight patients were evaluated by a board-certified neuroradiologist. All patients had skull base dysplasia, most with an unusual coronal basioccipital cleft (7/8). All brain MR exams showed microcephaly, volume loss and gyral simplification (5/5). Six patients had an absent massa intermedia. Four patients had small globe anterior segments; three had optic pathway hypoplasia. Basilar artery fenestration was present in two patients; vertebrobasilar hypoplasia was present in one patient. The inner ear vestibules were dysplastic in two patients. One patient had pachymeningeal thickening. Spinal anomalies included scoliosis, segmentation anomalies, endplate irregularities, basilar invagination, foramen magnum stenosis and tethered spinal cord. Typical imaging manifestations of Cornelia de Lange syndrome include skull base dysplasia with coronal clival cleft, cerebral and brainstem volume loss, and gyral simplification. Membranous labyrinth dysplasia, anterior segment and optic pathway hypoplasia, basilar artery fenestration, absent massa intermedia and spinal anomalies may also be present. (orig.)

  16. Obituary: Andrew Lange (1957-2010)

    Kamionkowski, Marc

    2011-12-01

    The worlds of physics and astrophysics were stunned to learn on 22 January 2010 that Andrew Lange, the Marvin L. Goldberger Professor of Physics at Caltech, had taken his own life the night before. He had succumbed to the severe depression that he had suffered from for many years, unbeknownst to even his closest colleagues. Lange will perhaps be best remembered as the co-leader of Boomerang, the balloon-borne experiment that provided the first high-angular-resolution map of the cosmic microwave background (CMB). And while this was certainly his most notable achievement, Andrew amassed a record of accomplishment as an instrumentalist, leader, mentor, and communicator that extended much further. Andrew was born in Urbana, Illinois on July 23, 1957, the son of an architect and a librarian, and raised primarily in Connecticut. His family and early friends remember him as a serious and extremely intelligent child and young man. Andrew Lange's lifelong interest in the CMB was nurtured as an undergraduate at Princeton University by David Wilkinson, and he recalled fondly a summer spent working with John Mather at Goddard Space Flight Center. Andrew Lange went to graduate school in physics at Berkeley where he worked in Paul Richards' group. Although his thesis project, the Berkeley-Nagoya rocket experiment, showed an anomalous sub-millimeter excess in the CMB spectrum that was shortly thereafter shown by a later flight of the same rocket and COBE-FIRAS to be incorrect, Lange's talents were recognized by the physics department at Berkeley who appointed him shortly after his PhD (1987) to their faculty. While on the Berkeley faculty, Andrew obtained early detections of the Sunyaev-Zeldovich effect, upper limits to small-angle CMB fluctuations, and important infrared constraints to the interstellar medium. He also led a pioneering instrument operating 300 mK detectors for a small infrared satellite experiment. This early work showed high ambition and daring, and it pioneered

  18. Environmental Survey at Ormen Lange, June 2009

    Energy Technology Data Exchange (ETDEWEB)

    2010-07-01

    An environmental monitoring survey was carried out at Ormen Lange in Region V on behalf of Norske Shell. The samples were collected at 19 stations by use of a 0.25 m{sub 2} box corer and carried out in connection with the field work in Region VI. The station depths varied between 823 and 925 m. The sediments at Ormen Lange are classified as silt with a high amount of pelite (> 90 %) and TOM (> 9 %). The amount of pelite is higher than that found in the baseline survey in 2004 at all stations. Whether this is a result of changes in sediment composition or a difference in analytical methods used is not known. With the exception of station OL-01 and OL-09, where a small increase has occurred, the amount of TOM has decreased at the stations since 2004. The concentrations of hydrocarbons and metals in the sediments at Template D, can be regarded as the natural background level for these parameters. The average amount of THC in the sediments around Template D is 11.7 +- 1.8 mg/kg in this base line survey. The average level of THC at template A and B was at the same level in the base line survey in 2004, 9.7 +- 0.6 mg/kg. In the present survey the average amount of THC in the sediments at Template A and B has increased to 17.0 +- 3.9 mg/kg. 11 of 14 stations at Template A and B have slightly elevated levels of barium and zinc in the sediments and sediments at three stations are elevated with mercury. In the present survey the mollusks dominates the fauna at Ormen Lange. The number of individuals at the stations (0.4 m{sub 2}) is high (1553 - 2833), while the number of taxa is relatively low (51 - 73), resulting in a very low diversity (H' 2.4 - 3.3). This is due to the over dominance by two mussels (Thyasira minuta and T. equalis) at all stations. However, the dominant species registered are known to be abundant in sediment with high amount of pelite and organic material. Due to the different sampling strategy and area, a direct comparison with the baseline survey is

    Cornelia de Lange Syndrome (CdLS) (also called Bushy Syndrome or Amsterdam dwarfism), is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth), upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    Cornelia de Lange is a genetic syndrome which affects between 1/10.000 and 1/60.000 neonates, but its genetic bases are still not clear. Its principal clinical characteristics are the delay in growth and development, hirsute, structural anomalies in the limbs and distinctive facial characteristic. Dental problems are frequent and include: ogival palate, micrognathia, dental malalignment, delayed teething, microdontic teeth, periodontal disease and dental erosion produced by gastric reflux. Discussed is the case of a 29 year old patient affected by the syndrome in question, which presents the principal clinical characteristics. The patient's general state of health is acceptable, without cardiac or respiratory alterations. The intraoral exploration shows policaries, periodontal disease, persistence of the temporal teeth and ectopic molars. After completing the necessary pre-operatory preparations, the entire odontological treatment was carried out under general aesthesia, due to the patient's total lack of collaboration. PMID:17909511

  9. Arc Magma Genesis from Melting of Mélange Diapirs

    Science.gov (United States)

    Cruz-Uribe, A. M.; Marschall, H.; Gaetani, G. A.

    2015-12-01

    Alkaline basalts occur in many subduction-related volcanic settings, including the Sunda, Izu-Bonin, Honshu, Aeolian, and Aleutian arcs, yet their origin continues to be debated. Recent studies have suggested that buoyant material (mélange) from the slab-wedge interface may rise into the hot corner of the mantle wedge as low-density plumes or diapirs, where it will melt or induce mantle melting due to dehydration. High-pressure mélange rocks represent a mixture of mafic, ultramafic, and sedimentary components, and are often dominated by chlorite. Mélange rocks are also enriched in accessory phases such as monazite, zircon, and rutile, which host a variety of trace elements. We present results from experimental melting of chlorite-rich mélange material at mantle wedge conditions that reproduce many of the compositional features of subduction-related lavas. Piston cylinder experiments were performed at conditions appropriate for mantle wedge diapirs (1030-1280 °C, 1.5-2.5 GPa) using natural mélange rocks from Syros, Greece. Experimental melts derived from omphacite-epidote-phengite bearing chlorite schists range in composition from basaltic trachyandesites to trachydacites to more alkaline melt compositions (50.7-60.73 wt% SiO2, 7.48-12.93 wt% Na2O+K2O). All of the experimental melts are characterized by high alumina contents (16.79-21.36 wt% Al2O3). Minerals coexisting with these melts include clinopyroxene, amphibole (at lower T) or olivine (at higher T), garnet (at higher P), ilmenite and/or rutile, and zircon. Trace element patterns in our experimentally produced melts are similar to those from arc volcanoes worldwide. Experimental melts are enriched in large ion lithophile elements (Cs, Rb, Ba, K, Pb, Sr) and depleted in high field strength elements (Nb, Ta, and Ti). Zirconium and Hf are enriched relative to the rare earth elements (REE), which show flat to heavy REE depleted patterns depending on the presence of residual garnet. Thorium is fractionated

    We report on the derivation of the discrete complex Ginzburg-Landau equation with first- and second-neighbor couplings using a nonlinear electrical network. Furthermore, we discuss theoretically and numerically modulational instability of plane carrier waves launched through the line. It is pointed out that the underlying analysis not only spells out the discrete Lange-Newell criterion by the means of the linear stability analysis at which the modulational instability occurs for the generation of a train of ultrashort pulses, but also characterizes the long-time dynamical behavior of the system when the instability grows.

    Full Text Available The long QT syndrome (LQTS is a cause of syncope and sudden death. Jervell and Lange-Nielson syndrome (JLNS is an uncommon form of LQTS, having autosomal recessive transmission, and is associated with congenital deafness. We report a case of JLNS in a child who presented to us with refractory epilepsy. The cardiac cause of seizures was suspected as the child was hypotensive and pulseless during the episode of seizures. The child was diagnosed as JLNS based on Schwartz diagnostic criteria for LQTS and congenital sensorineural deafness. The child responded well to β-blocker therapy. Antiepileptic drugs were stopped. The screening of family members with ECG revealed a QT interval more than required for diagnosis of LQTS but they were asymptomatic. All asymptomatic family members were also put on metoprolol. All of them showed great improvement with the reduction of the QT interval on ECG. The patient was doing well on immediate follow-up.

    Cornelia de Lange Syndrome (CdLS) is a rare genetic disorder caused by mutations in the cohesion complex and its regulators. The syndrome is characterized by multiple organ system abnormalities, pre- and post-natal growth retardation and typical facial features. Thrombocytopenia is a reduction in platelet count to <150 × 10(9)  L. It can be caused by congenital or acquired decreased production, increased destruction, or sequestration of platelets. In recent years, several papers reported thrombocytopenia and immune thrombocytopenia in patients affected by CdLS. In 2011, Lambert et al. estimated the risk of idiopathic thrombocytopenia purpura in CdLS patients to be 31-633 times greater than in the general population. We describe the incidence of thrombocytopenia in 127 Italian CdLS patients, identifying patients with transient or persistent thrombocytopenia, but a lower incidence of true idiopathic thrombocytopenic purpura (ITP).

  6. Repensar la criminología con Luhmann, Lang, Foucault

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available El tema que el artículo afronta es: ¿cuál es el objeto de la criminología? Para responder a esta pregunta es necesario analizar el estatuto epistemológico delsaber criminológico. Pero si se busca una respuesta a este problema dentro del debate criminológico, se quedará desilusionado. La criminología parece no darse plenamente cuenta de la necesidad de un método capaz de hacer posible una comprensión de su propio objeto. El autor propone seguir tres caminosque, desde perspectivas diferentes, afrontan el problema fundamental para cada observación social, es decir, el hecho de que cada observación de la sociedad es parte de lo que se quiere describir. El primer recorrido propuesto es la teoría de los sistemas sociales de Niklas Luhmann. Mediante la distinción entre observación de primer y de segundo orden es posible comprender el problema del objeto sin caer en la paradoja de la autoimplicación. El segundo recorrido propuesto es una obra de arte y precisamente el film de Frit Lang M., El monstruo de Dusseldorf. El arte, en efecto, permite ver lo que no podemos ver dentro de los confines de una observación científica. El arte permite rodear el punto ciego de la propia observación. Por último, el tercer recorrido propuesto al lector es la genealogía del poder descrita por Michel Foucault en el curso al College de France de 1974-1975, dedicado a los Anormales Estos tres recorridos permiten comprender desde perspectivas diferentes que la criminología no podrá producir conocimientos suficientemente adecuados a su objeto si no comprende cómo ella misma está siempre implicada en la construcción del objeto que observa.

  8. Friedrich Albert Lange on neo-Kantianism, socialist Darwinism, and a psychology without a soul.

    Science.gov (United States)

    Teo, Thomas

    2002-01-01

    Friedrich Albert Lange was a German philosopher, political theorist, educator, and psychologist who outlined an objective psychology in the 1860s. This article shows how some of the most important worldviews of the nineteenth century (Kantianism, Marxism, and Darwinism) were combined creatively in his thought system. He was crucial in the development of neo-Kantianism and incorporated psycho-physiological research on sensation and perception in order to defend Kant's epistemological idealism. Based on a critique of phrenology and philosophical psychology of his time, Lange developed a program of a psychology without a soul. He suggested that only those phenomena that can be observed and controlled should be studied, that psychology should focus on actions and speech, and that for each psychological event the corresponding physical or physiological processes should be identified. Lange opposed introspection and subjective accounts and promoted experiments and statistics. He also promoted Darwinism for psychology while developing a socialist progressive-democratic reading of Darwin in his social theory. The implications of socialist Darwinism on Lange's conceptualization of race are discussed and his prominence in nineteenth century philosophy and psychology is summarized. PMID:12115788

    2012-03-01

    Full Text Available The long-standing friendship between Andrew Lang (1844-19121 and Henry RiderHaggard (1856-19252 is surely one of the most intriguing literary relationships ofthe Victorian era.3 Lang was a pre-eminent literary critic and his support forHaggard’s earliest popular romances, such as King Solomon’s mines (1885 andShe (1887, helped to establish them as leading models of the new genre ofimperial adventure fiction.4 Lang and Haggard co-authored The world’s desire(18905 and the ideas of Lang, who was also a brilliant Classics scholar, can beseen in many of Haggard’s works. There are some significant similarities betweenthe two men: both were approximate contemporaries who lived through the mostaggressive phase of British imperialism, both were highly successfully writers whoearned their living by their pens, both wrote prolifically and fluently on a wide range of subjects,6 both were largely self-educated, both were interested in thesupernatural, both had had unhappy experiences in love at first but later maintainedlong-lasting marriages, and both were men with powerful faculties of imagination.There are, of course, significant differences also: Lang was a gifted intellectualwho had won a fellowship at Oxford, a Homeric scholar, a poet with a gift forirony and humour, and one of the earliest exponents of the new science ofanthropological mythology; Haggard was less well educated and more seriousminded,he preferred action to ideas, was personally involved in the extension ofBritish rule in Southern Africa,7 and had a close experience of African tribal life.This article sets out to investigate the relationship between these two men, and toassess the extent to which Lang’s classical and anthropological thinking shaped thenarratives of Haggard, especially those set in his imperialistic fantasy of theAfrican continent.

  14. Toxicity of phosphor esters: Willy Lange (1900-1976) and Gerda von Krueger (1907-after 1970).

    In 1851 Williamson serendipitously discovered a new and efficient way to produce ethers using ethyl iodide and potassium salts. Based on this new synthetic approach, the Frenchman Philippe de Clermont and the Muscovite Wladimir Moschnin, both élèves of Adolphe Wurtz in his Paris School of Chemistry, achieved the synthesis of the first ester of pyrophosphoric acid (TEPP). de Clermont "tasted" the new compound and although TEPP is a potent cholinesterase inhibitor he failed to recognize its toxicity. Almost a century later, in 1932, Willy Lange (1900-1976) and his graduate student Gerda v. Krueger (1907-after 1970) described the toxicity of organophosphonates. While the classic paper of the two "Uber Ester der Monofluorphosphorsäure." is cited by almost everybody working in the field, little is known about Lange and almost nothing about v. Krueger. This brief communication attempts to shed some light on the life of both. PMID:21105582

  15. Effects of herbicides on Behr's metalmark butterfly, a surrogate species for the endangered butterfly, Lange's metalmark.

    Stark, John D; Chen, Xue Dong; Johnson, Catherine S

    2012-05-01

    Lange's metalmark butterfly, Apodemia mormo langei Comstock, is in danger of extinction due to loss of habitat caused by invasive exotic plants which are eliminating its food, naked stem buckwheat. Herbicides are being used to remove invasive weeds from the dunes; however, little is known about the potential effects of herbicides on butterflies. To address this concern we evaluated potential toxic effects of three herbicides on Behr's metalmark, a close relative of Lange's metalmark. First instars were exposed to recommended field rates of triclopyr, sethoxydim, and imazapyr. Life history parameters were recorded after exposure. These herbicides reduced the number of adults that emerged from pupation (24-36%). Each herbicide has a different mode of action. Therefore, we speculate that effects are due to inert ingredients or indirect effects on food plant quality. If these herbicides act the same in A. mormo langei, they may contribute to the decline of this species. PMID:22310058

  16. MyProLang - My Programming Language: A Template-Driven Automatic Natural Programming Language

    CERN Document Server

    2012-01-01

    Modern computer programming languages are governed by complex syntactic rules. They are unlike natural languages; they require extensive manual work and a significant amount of learning and practicing for an individual to become skilled at and to write correct programs. Computer programming is a difficult, complicated, unfamiliar, non-automated, and a challenging discipline for everyone; especially, for students, new programmers and end-users. This paper proposes a new programming language and an environment for writing computer applications based on source-code generation. It is mainly a template-driven automatic natural imperative programming language called MyProLang. It harnesses GUI templates to generate proprietary natural language source-code, instead of having computer programmers write the code manually. MyProLang is a blend of five elements. A proprietary natural programming language with unsophisticated grammatical rules and expressive syntax; automation templates that automate the generation of in...

    International Nuclear Information System (INIS)

    Maximizing the physics performance of detectors being designed for the International Linear Collider, while remaining sensitive to cost constraints, requires a powerful, efficient, and flexible simulation, reconstruction and analysis environment to study the capabilities of a large number of different detector designs. The preparation of Letters Of Intent for the International Linear Collider involved the detailed study of dozens of detector options, layouts and readout technologies; the final physics benchmarking studies required the reconstruction and analysis of hundreds of millions of events. We describe the Java-based software toolkit (org.lcsim) which was used for full event reconstruction and analysis. The components are fully modular and are available for tasks from digitization of tracking detector signals through to cluster finding, pattern recognition, track-fitting, calorimeter clustering, individual particle reconstruction, jet-finding, and analysis. The detector is defined by the same xml input files used for the detector response simulation, ensuring the simulation and reconstruction geometries are always commensurate by construction. We discuss the architecture as well as the performance.

    2016-05-01

    Cornelia de Lange syndrome is a multisystemic developmental disorder mainly related to de novo heterozygous NIPBL mutation. Recently, NIPBL somatic mosaicism has been highlighted through buccal cell DNA study in some patients with a negative molecular analysis on leukocyte DNA. Here, we present a series of 38 patients with a Cornelia de Lange syndrome related to a heterozygous NIPBL mutation identified by Sanger sequencing. The diagnosis was based on the following criteria: (i) intrauterine growth retardation and postnatal short stature, (ii) feeding difficulties and/or gastro-oesophageal reflux, (iii) microcephaly, (iv) intellectual disability, and (v) characteristic facial features. We identified 37 novel NIPBL mutations including 34 in leukocytes and 3 in buccal cells only. All mutations shown to have arisen de novo when parent blood samples were available. The present series confirms the difficulty in predicting the phenotype according to the NIPBL mutation. Until now, somatic mosaicism has been observed for 20 cases which do not seem to be consistently associated with a milder phenotype. Besides, several reports support a postzygotic event for those cases. Considering these elements, we recommend a first-line buccal cell DNA analysis in order to improve gene testing sensitivity in Cornelia de Lange syndrome and genetic counselling. PMID:26701315

Cornelia de Lange syndrome is associated with abnormalities on chromosomes 5, 10 and X. Heterozygous point mutations in three genes (NIPBL, SMC3 and SMC1A, are responsible for approximately 50-60% of CdLS cases. CdLS is characterized by autistic features, notably excessive repetitive behaviors and expressive language deficits. The prevalence of autism spectrum disorder (ASD symptomatology is comparatively high in CdLS. However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. A significantly higher prevalence of self-injury are evident in CdLS. Self-injury was associated with repetitive and impulsive behavior. This study describes the behavioral phenotype of four children with Cornelia de Lange syndrome and ASDs and rehabilitative intervention that must be implemented.

  5. Lawsonite Blueschists in Recycled Mélange Involved in K-Rich Orogenic Magmatism

    2014-12-01

    The origin of K-rich orogenic magmatism in the Alpine-Himalayan belt and its relationship to the large-scale elevations in several massifs of the orogen is controversial, particularly the significance of the widespread presence of a geochemical signal typical for recycled continental crust. Two competing scenarios invoke direct melting of continental crust during deep intercontinental subduction and removal of heavily metasomatised mantle lithosphere by delamination into the convecting mantle. Here we investigate the coupling of high Th/La ratio with crustal isotopic signatures in K-rich orogenic lavas that does not occur in volcanic rocks from other collisional environments to distinguish between these two models. High-pressure experimental results on a phyllite representing upper crustal composition and a detailed mineral and geochemical study of blueschists from Tavşanlı mélange, Turkey, indicate that this geochemical fingerprint originates by melting of subducted mélange. Melting of crust at the top of the subducted continental lithosphere cannot produce observed fingerprint, whereas lawsonites, especially those with terrigenous sediment origin from blueschists with high Th/La can. Lawsonites that grow in various components of a subduction mélange inherit the geochemical characteristics of either oceanic or continental protoliths. It is currently uncertain whether those carrying the high Th/La signature originate by direct melting of continental blocks in the mélange or by the introduction of supercritical fluids from lawsonite blueschist of continental origin that infiltrate oceanic sediment blocks. Either way, the high Th/La is later released into subsequently formed melts. This confirms the supposition that lawsonite is the main progenitor of the high Th/La and Sm/La ratio. However, lawsonite must break down completely to impart this unique feature to subsequent magmas. The source regions of the potassic volcanic rocks consist of blueschist facies mélanges

    Full Text Available Desde hace algunos años, un limitado grupo de empresas citrícolas trabaja en la producción de cítricos orgánicos (Ceiba, Morón, Arimao en las cuales se necesita mecanizar el proceso de distribución de grandes volúmenes de materia orgánica. Teniendo en cuenta las altas normas de entrega (12 t/ha, que implica la entrega de 3 t/hilera y 600 t/año, se hace necesario el estudio de esparcidoras de gran capacidad, resistencia y durabilidad, además de satisfacer las exigencias de distribución en cítricos, sobre todo porque se requiere distribuir materia orgánica debajo de la copa de los árboles en una franja continua de ancho no menor de 0,5m (38,46 kg/planta. La efectividad del cumplimiento de estas normas se contrapone con los efectos de compactación del suelo, sobre todo cuando la calle de las plantaciones está plantada de cultivos en rotación como leguminosas y otros. El trabajo tiene el objetivo de analizar las ventajas e inconvenientes que presentan las principales máquinas distribuidoras existentes en el mercado, de acuerdo con las nuevas condiciones que exigen los cítricos orgánicos. Por tanto, los parámetros: capacidad de entrega, volumen de tolva, compactación del suelo, ancho de distribución, efectividad de mecanismos de distribución, entrega lateral a baja altura y por encima de las leguminosas, constituyen los principales elementos de selección. En el análisis se considera el factor económico como uno de los elementos decisivos en la selección de las mejores opciones. Del análisis se concluye que debe disponerse de un dispositivo adaptado a la salida de una máquina distribuidora con mecanismo variador de la altura de distribución, para lograr diferentes condiciones de lanzamiento

    Full Text Available Les mélanges de polymères thermoplastiques font actuellement l'objet d'un effort considérable de recherche et de développement. Cette synthèse bibliographique concerne principalement les mélanges mécaniques de polymères incompatibles à l'état fondu. Ceux-ci ont une morphologie hétérogène qui dépend des conditions de mise en oeuvre autant que de la nature des constituants. De plus, pour ce type de matériaux, la nature de l'interface joue un rôle déterminant sur la formation de la morphologie hétérogène et donc sur les propriétés du produit final. D'autre part un problème important réside dans la stabilité des mélanges réalisés. L'ajout d'une faible quantité d'agent tensioactif de type copolymère séquencé, ou greffé, ou la modification chimique des constituants (greffage ou réticulation par exemple permet, dans certains cas d'améliorer très sensiblement les propriétés des mélanges en augmentant l'adhérence entre les phases immiscibles. L'ensemble de ces considérations permettent la réalisation industrielle de nouveaux matériaux polymères aux caractéristiques spécifiques. Thermoplastic polymer mixtures are currently the subject of considerable research and development efforts. This bibliographic synthesis deals mainly with melt blending process of incompatible polymers. These blends have a heterogeneous morphology that depends on the processing conditions as much as on the chemical structure of the componants. Likewise, for these materials the nature of the interface plays a decisive role on the formation of the heterogeneous morphology and hence on the properties on the end product. Furthermore, an important problem is to stabilize the morphology of the blends. Adding a small amount of surfactant of the sequenced of grafted copolymer type or, else, the chemical reaction of the constituents (e. g. grafting or branching during processing are ways in some cases of considerably improving the properties of

    We present a case of a young adult with both Cornelia de Lange syndrome and Ehlers-Danlos syndrome. The patient showed non-verbal autism, intellectual disability and severe/intractable self-harming behaviours that led to a life-threatening complication (ie, septicaemia). A significant reduction in the self-harming behaviours was attained in a multidisciplinary neurobehavioural inpatient unit after addressing all causes of somatic pains, managing pain using level II and III analgesics, stabilising the patient's mood, limiting the iatrogenic effects of multiple prescriptions and offering a specific psychoeducational approach.

  12. Effects of herbicides on Behr's metalmark butterfly, a surrogate species for the endangered butterfly, Lange's metalmark

    International Nuclear Information System (INIS)

    Lange's metalmark butterfly, Apodemia mormo langei Comstock, is in danger of extinction due to loss of habitat caused by invasive exotic plants which are eliminating its food, naked stem buckwheat. Herbicides are being used to remove invasive weeds from the dunes; however, little is known about the potential effects of herbicides on butterflies. To address this concern we evaluated potential toxic effects of three herbicides on Behr's metalmark, a close relative of Lange's metalmark. First instars were exposed to recommended field rates of triclopyr, sethoxydim, and imazapyr. Life history parameters were recorded after exposure. These herbicides reduced the number of adults that emerged from pupation (24–36%). Each herbicide has a different mode of action. Therefore, we speculate that effects are due to inert ingredients or indirect effects on food plant quality. If these herbicides act the same in A. mormo langei, they may contribute to the decline of this species. - Highlights: ► We evaluated the effects of three herbicides on the butterfly, Behr's metalmark. ► These herbicides are used to control invasive weeds in butterfly habitat. ► The herbicides reduced adult butterfly emergence. - Herbicides are used to remove invasive weeds from butterfly habitat. Certain herbicides may be having a negative effect on butterflies.

    This study sheds light on the tectonic and structural knowledge of the mélange facies located to the south of Chañaral city, Chile. The Chañaral mélange has been related to an accretionary prism at the western active continental margin of Gondwana. Based on the fossil content, the original turbidite sequence would have been deposited during Devonian to Carboniferous times. The Chañaral mélange is included in the Las Tórtolas Formation, which corresponds to the Paleozoic metasedimentary basement located in the Coastal Range in northern Chile. It consists of a monotonous sequence of more than 90% of interbedded sandstones and shales, with a few limestones, pelagic chert, conglomerates and basic volcanic rocks, metamorphosed to the greenschist facies. In the study area, the Las Tórtolas Formation is divided into two structural domains separated by a major reverse dextral structure, called here the Infieles fault. To the east, the Las Tórtolas Formation is characterized by a brittle-ductile deformation, defined by the original sedimentary contacts in the turbiditic sequence. Besides, thrust faults and associated thrust propagation folds promotes a penetrative axial plane foliation. Mélange facies are located to the west of the Infieles fault. Although lithologies comprising this domain are similar to the rest of the Las Tórtolas Formation, mélange facies (ductile domain) are characterized by the complete disruption of the original architecture of the turbidite succession. The most significant structures in the mélange are the ubiquitous boudinage and pinch and swell structures, asymmetric objects, S-C structures and tight to isoclinal folds. This deformation is partitioned in the Chañaral mélange between linear fabric domains (L), characterized by quartzite blocks with prolate shape in a phyllite matrix with pencil structures, and linear-planar fabric domains (L-S), where quartzite objects show oblate shape and phyllites present a penetrative foliation

    1996-03-01

    The efficacy of the neurotrophic peptide ORG 2766 in diabetic patients with polyneuropathy was evaluated in a double-blind, placebo-controlled, multicentre trial. One hundred and twenty four patients were randomised in five groups to receive 0.1, 0.4, 2 or 5 mg ORG 2766 or placebo, once daily, administered subcutaneously 52 weeks. Thermal discrimination thresholds (TDT) and vibration perception thresholds (VPT), motor and sensory nerve conduction velocity, Hoffmann reflex, heart rate variation during deep breathing and heart rate response after standing up, neurological examination score and neuropathic symptom score were determined at baseline and after 17, 34 and 52 weeks of treatment. Of the nerve function indices studied, at week 52 the TDTwarmth of the hand in the ORG 2766 0.1, 0.4 and 5 mg groups and the TDTcold of the foot in the ORG 2766 0.1 and 0.4 mg groups significantly improved compared with placebo. Further significant improvement as compared with placebo was observed in the paraesthesia score at week 34 and week 52 in the ORG 2766 2 mg group. Only at week 34 had both the heartbeat variation during deep breathing and the VPT of the foot in the ORG 2766 0.1 mg group improved significantly, compared with placebo. No further statistically significant differences were observed at time for the other measures. No adverse reactions were observed. The only recorded drug-induced side effect was pain at the injection site. Taking all measures of efficacy into account, the statistically significant results observed did not show consistency within each measure. Therefore, it is concluded that ORG 2766, in contrast to earlier reports, is not effective in treating diabetic polyneuropathy. PMID:8936356

    As a rare multisystem congenital anomaly disorder, Cornelia de Lange syndrome (CdLS) is featured by delayed growth and development, distinct facial dimorphism, limb malformations and multiple organ defects. CdLS is a genetic syndrome affecting 1/10000-1/60000 neonates with unknown genetic basis. Delayed growth and development, hirsute, structural anomalies of the limbs and distinct facial dimorphism are considered as its main clinical characteristics. Introducing CdLS cases of different ethnic backgrounds could add distinctions to the phenotypic picture of the syndrome and be useful in diagnosis. Early diagnosis and decreased death rates are achievable through enhanced awareness on this syndrome. We present here a 45-day-old girl, as the first case of Cornelia in Golestan (Northern Iran), referred to our hospital with the symptoms as mentioned above. PMID:27042551

  16. Low-frequency fluctuations in vertical cavity lasers: Experiments versus Lang-Kobayashi dynamics

    International Nuclear Information System (INIS)

    The limits of applicability of the Lang-Kobayashi (LK) model for a semiconductor laser with optical feedback are analyzed. The model equations, equipped with realistic values of the parameters, are investigated below the solitary laser threshold where low-frequency fluctuations (LFF's) are usually observed. The numerical findings are compared with experimental data obtained for the selected polarization mode from a vertical cavity surface emitting laser (VCSEL) subject to polarization selective external feedback. The comparison reveals the bounds within which the dynamics of the LK model can be considered as realistic. In particular, it clearly demonstrates that the deterministic LK model, for realistic values of the linewidth enhancement factor α, reproduces the LFF's only as a transient dynamics towards one of the stationary modes with maximal gain. A reasonable reproduction of real data from VCSEL's can be obtained only by considering the noisy LK or alternatively deterministic LK model for extremely high α values

    Full Text Available The article presents an unofficial discussion that took place between one of the most prominent Polish critics of the late 19th century and Antoni Lange, a raising poet of the 90s, whose work had gained little attention from the older colleague. Mentioned briefly in Chmielowski’s Współczesni poeci polscy in 1895, Lange responded to some of the critic’s fterwards. Chmielowski did not respond to that directly, however, his review of Lange’s volume of poetry published at the time and the will to defend his claims using the adversary’s poetry as a pretext shows that the young poet had succeeded in provoking the respected critic to take defensive position. The two writers, discussing an ongoing ‘crisis’ of poetry, present their own perspectives on the roots of the situation. Chmielowski’s claims from the beginning of the 20th century prove that the dispute, unofficial as it was, was won by Antoni Lange.

    Facial analysis systems are becoming available to healthcare providers to aid in the recognition of dysmorphic phenotypes associated with a multitude of genetic syndromes. These technologies automatically detect facial points and extract various measurements from images to recognize dysmorphic features and evaluate similarities to known facial patterns (gestalts). To evaluate such systems' usefulness for supporting the clinical practice of healthcare professionals, the recognition accuracy of the Cornelia de Lange syndrome (CdLS) phenotype was examined with FDNA's automated facial dysmorphology novel analysis (FDNA) technology. In the first experiment, 2D facial images of CdLS patients with either an NIPBL or SMC1A gene mutation as well as non-CdLS patients which were assessed by dysmorphologists in a previous study were evaluated by the FDNA technology; the average detection rate of experts was 77% while the system's detection rate was 87%. In the second study, when a new set of NIPBL, SMC1A and non-CdLS patient photos was evaluated, the detection rate increased to 94%. The results from both studies indicated that the system's detection rate was comparable to that of dysmorphology experts. Therefore, utilizing such technologies may be a useful tool in a clinical setting. PMID:26663098

    In a newborn boy with characteristics of Brachmann-de Lange syndrome (BDLS), high temperatures were observed on the second day after birth and recurred 2-6 times daily during the 7 months of the patient`s life. After, transient hypertonia hypotonia developed. In muscle biopsy specimen taken on the 51st day of life, serious and progressive distortion of mitochondria was observed. In several mitochondria the cristae structure was broken, other mitochondria were shrunken and the damage progressed towards further deterioration in other organelles. At several points between the myofibrils, amorphous material was seen, possibly debris of destroyed mitochondria. Most myofibrils seemed to be intact; however, in some areas myolytic signs were present. Analysis of the mitochondrial DNA (mtDNA) showed multiple deletions in skeletal and heart muscles, liver, lung and kidney. Since the mtDNA encodes several proteins of the respiratory complexes, the deleted mtDNA certainly affected the integrity of the mitochondrial oxidative phosphorylation process by synthesis of abnormal proteins. In the present case the hyperthermia may have been a result of the mtDNA damage. 13 refs.

    2010-12-01

    Cornelia de Lange syndrome (CdLS) is a rare, congenital syndrome characterized by growth retardation, dysmorphic face, mental retardation and limb reduction defects. Clinical manifestations of CdLS can be extremely variable. Mutations in NIPBL, SMC1A and SMC3 genes, encoding for a regulator and two subunits of the cohesin complex, respectively, are found in 60-65% of CdLS patients. We report on a male with CdLS who is mosaic for the c.2827delA mutation in the NIPBL gene. Allele quantitation by pyrosequencing showed the presence of the mutation in about 10% and 33% of DNA samples from peripheral blood and buccal smears, respectively. The patient shows a complex phenotype: growth and psychomotor retardation are characteristic of the severe forms of CdLS, while the absence of severe limb reduction defects and major malformations are typical of the mild phenotype. He also has depigmentation areas following Blashko lines, an unusual finding in CdLS, which has been associated with mosaicism in other genetic conditions. This case represents the first evidence of somatic mosaicism in CdLS and explains the mild phenotype in the patient as compared to that predicted by a truncating mutation. Besides confirming the clinical and genetic heterogeneity of CdLS, this case also raises the likely underestimated mutation rate of known genes and points to the complexity of addressing genotype-phenotype correlations.

    Full Text Available Cornelia de Lange Syndrome (CdLS (also called Bushy Syndrome or Amsterdam dwarfism, is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth, upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    Full Text Available Abstract Background Cornelia de Lange syndrome (CdLS is a dominantly inherited disorder characterized by facial dysmorphism, growth and cognitive impairment, limb malformations and multiple organ involvement. Mutations in NIPBL gene account for about 60% of patients with CdLS. This gene encodes a key regulator of the Cohesin complex, which controls sister chromatid segregation during both mitosis and meiosis. Turner syndrome (TS results from the partial or complete absence of one of the X chromosomes, usually associated with congenital lymphedema, short stature, and gonadal dysgenesis. Case presentation Here we report a four-year-old female with CdLS due to a frameshift mutation in the NIPBL gene (c.1445_1448delGAGA, who also had a tissue-specific mosaic 45,X/46,XX karyotype. The patient showed a severe form of CdLS with craniofacial dysmorphism, pre- and post-natal growth delay, cardiovascular abnormalities, hirsutism and severe psychomotor retardation with behavioural problems. She also presented with minor clinical features consistent with TS, including peripheral lymphedema and webbed neck. The NIPBL mutation was present in the two tissues analysed from different embryonic origins (peripheral blood lymphocytes and oral mucosa epithelial cells. However, the percentage of cells with monosomy X was low and variable in tissues. These findings indicate that, ontogenically, the NIPBL mutation may have appeared before the mosaic monosomy X. Conclusions The coexistence in several patients of these two rare disorders raises the issue of whether there is indeed a cause-effect association. The detailed clinical descriptions indicate predominant CdLS phenotype, although additional TS manifestations may appear in adolescence.

    Cornelia De Lange syndrome (CdLS) is a rare congenital disease characterized by typical facial dysmorphism, developmental disability, and limb deficiency defects. Various congenital malformations and medical complications have been described with gastroesophageal reflux as the major one. CdLS patients often require multiple high-risk anesthetic procedures. At San Gerardo Hospital (Monza, Italy) the management of CdLS patients is routinely organized through a standard protocol and a dedicated pediatric anesthesia team has been implemented. We report on a retrospective descriptive analysis of the anesthetic records of the CdLS patients admitted to San Gerardo Hospital from January 2010 to December 2015. We retrieved: demographics, genetic profiles, type of procedures, anesthetic approaches, anesthetics usage and complications. Data are reported as median (interquartile range) values. Twenty-seven patients (11 female), with age 12 (7-15) years old, weight 24 (14-35) kg, and severity score of 25 (18-32) were included. NIBPL mutations were the most frequently represented. We analyzed 58 procedures (30 esophagogastroduodenoscopies, 8 evoked auditory potential tests, 5 radiodiagnostics, 5 catheters positioning, 4 bronchoscopies) managed by sedation (36) and general anesthesia (6). Each patient underwent one (1-2) anesthetic procedure. Propofol (59%), sevoflurane (31%), fentanyl (24%), and ketamine (10%) were used. Three out of six endotracheal intubations were difficult. The only documented intraoperative complications were three episodes of desaturation (oxygen saturation <90%) occurring during sedations and were managed without the need for an invasive control of the airways. Implementation of a specific management protocol and a dedicated allowed to provide anesthesia to CdLS patients without the occurrence of major complications. © 2016 Wiley Periodicals, Inc.

  5. Interpretation of tracer tests performed in fractured rock of the Lange Bramke basin, Germany

    Science.gov (United States)

    Maloszewski, Piotr; Herrmann, Andreas; Zuber, Andrzej

    Two multitracer tests performed in one of the major cross-fault zones of the Lange Bramke basin (Harz Mountains, Germany) confirm the dominant role of the fault zone in groundwater flow and solute transport. Tracers having different coefficients of molecular diffusion (deuterium, bromide, uranine, and eosine) yielded breakthrough curves that can only be explained by a model that couples the advective-dispersive transport in the fractures with the molecular diffusion exchange in the matrix. For the scale of the tests (maximum distance of 225m), an approximation was used in which the influence of adjacent fractures is neglected. That model yielded nearly the same rock and transport parameters for each tracer, which means that the single-fracture approximation is acceptable and that matrix diffusion plays an important role. The hydraulic conductivity of the fault zone obtained from the tracer tests is about 1.5×10-2m/s, whereas the regional hydraulic conductivity of the fractured rock mass is about 3×10-7m/s, as estimated from the tritium age and the matrix porosity of about 2%. These values show that the hydraulic conductivity along the fault is several orders of magnitude larger than that of the remaining fractured part of the aquifer, which confirms the dominant role of the fault zones as collectors of water and conductors of fast flow. Résumé Deux multitraçages ont été réalisés dans l'une des zones principales de failles du bassin de Lange Bramke (massif du Harz, Allemagne); les résultats confirment le rôle prédominant de la zone de failles pour l'écoulement souterrain et le transport de soluté.

  12. Geochemistry and geochronology of HP mélanges from Tinos and Andros, cycladic blueschist belt, Greece

    2010-06-01

    U-Pb zircon geochronology, Sr-Nd isotope and bulk-rock geochemistry have been applied to meta-igneous and meta-sedimentary rocks from high-pressure metamorphic mélanges exposed on the Cycladic islands of Tinos, Syros and Andros. Ion microprobe (SHRIMP) U-Pb zircon dating of 7 samples representing meta-igneous blocks (Tinos), a blackwall zone (Tinos) and chlorite-talc schists from block-matrix contacts (Syros and Tinos) yielded Cretaceous ages of c. 80 Ma. Many of the criteria commonly used to distinguish between magmatic or metamorphic zircon genesis (internal structure, Th/U ratio, REE characteristics, Ti-in zircon thermometry, enclosed mineral phases) do not provide unambiguous constraints for the mode of formation. However, a magmatic origin for Cretaceous zircon of meta-gabbros and eclogites is considered likely. Supporting evidence for a previously suggested metamorphic origin for c. 80 Ma zircon in eclogite has not been found. Zircon of the same age occurring in chlorite-talc schists is presumably related to non-magmatic processes. Well-defined Cretaceous age groups clustering at c. 79 Ma also occur in the detrital zircon populations of 2 quartz mica schists representing the mélange matrix on Tinos, and suggest a much later time for sediment accumulation than previously assumed. The importance of c. 57 Ma zircon ages remains unclear, but may record either HP metamorphic processes or a post-57 Ma depositional age. The youngest age group in a third quartz mica schist from Tinos, collected outside the main mélange occurrences, clusters at c. 226-238 Ma. In all clastic metasediments from Tinos, most data points plot along the concordia between c. 300 and 900 Ma; single data points indicate concordant ages of c. 2.5 Ga, 2.3 Ga and 1 Ga, respectively. The youngest 206Pb/ 238U age group that has been recognized in a felsic paragneiss from Andros indicates an age of 163.1 ± 3.9 Ma, and mostly represents overgrowths around zircon with ages in the range from ˜ 272

  13. Aqueous Solubility of Hydrocarbon Mixtures Solubilité dans l'eau de mélanges d'hydrocarbures

    2006-12-01

    Full Text Available The solubility of hydrocarbon components in water is of great importance for the environmental sciences. Its prediction is usually based on using the pure component solubilities and the mole fraction of the components in the mixture. While the pure component solubilities are generally well known, few data exist on the solubility of mixtures. Using a simple relationship leads to an underestimation of the true solubility. This paper presents some new data on the aqueous solubility of binary hydrocarbon mixtures. Using a rigorous thermodynamic analysis, we explain the observed behavior, as well as other data from the literature, including the solubility of jet fuel mixtures in water. The activity coefficient models used for this purpose are NRTL, UNIQUAC and UNIFAC. Considering the small concentration in oil of some very soluble substances, the activity coefficient can become significant and thus explain the fact that solubilities of some component may be as much as twice as large as expected. La solubilité de composés hydrocarbonés dans l'eau est d'une importance cruciale pour les sciences environnementales. Sa prévision est généralement basée sur la solubilité des constituants purs et de leur fraction molaire en mélange. La solubilité des composés purs est généralement bien connue, mais peu de données ont été publiées concernant les mélanges. L'utilisation d'une relation simple conduit à une sous-estimation de la solubilité réelle. Cet article présente quelques données nouvelles de solubilités de mélanges hydrocarbonés simples. Une analyse thermodynamique rigoureuse permet de décrire la solubilité observée, aussi bien pour des mélanges modèles que pour des kérosènes. Les modèles de coefficient d'activité utilisés dans ce but sont NRTL, UNIQUAC et UNIFAC. Étant donné la faible concentration de certains constituants dans l'huile, leurs coefficients d'activité peut devenir important. Ceci explique une

  15. Formation of diamondiferous kyanite-eclogite in a subduction mélange

    Science.gov (United States)

    Aulbach, S.; Gerdes, A.; Viljoen, K. S.

    2016-04-01

    Diamond- and kyanite-bearing eclogites from the Lace kimberlite on the Kaapvaal craton have common picritic to gabbroic oceanic protoliths with bimineralic eclogites, lying on arrays of Eu∗ and ∑REE that are consistent with accumulation and fractionation of plagioclase and olivine. However, they also show significant compositional differences, such as more grossular-rich garnet and aluminous clinopyroxene (cpx), which require the operation of additional processes. Their nature is elucidated using mineral major- and trace-element compositions, as well as Sr isotope ratios determined by in situ techniques. Highly variable major-element compositions across the co-genetic eclogite suites exert a strong effect on the trace-element distribution between garnet and cpx, whereby Sc, Ge, Sr, Y, Cd, REE, Th and U partition more strongly into garnet with increasing grossular-content. Thus, significant differences between the trace-element compositions of garnet can ensue from crystal-chemical effects alone, making their use as petrogenetic indicators potentially ambiguous. After correcting for these compositional effects, garnet in kyanite-/diamond eclogites, and in eclogites devoid of accessory minerals but with similar signatures, shows depletion (or dilution) in Sc, Ge, Y, In, Zr, Hf and the HREE, and enrichment in the LREE and Th compared to garnet in bimineralic eclogites. This is interpreted as the signature of a pelite-derived melt, which was transferred by addition of aluminous cpx that later exsolved kyanite and garnet, as observed in other aluminous eclogite suites. Continental input can explain initial (at 2.9 Ga) 87Sr/86Sr ⩾ 0.714 measured in cpx in eleven samples with low 87Rb/86Sr (eclogites. We suggest that a subduction mélange is a favourable setting for the transfer of a sediment-derived signature into oceanic crust, leading to formation of diamondiferous kyanite-eclogites from bimineralic eclogites.

  16. On-line valve monitoring at the Ormen Lange gas plant

    International Nuclear Information System (INIS)

    The purpose of this presentation is to discuss replacing time and labor intensive nuclear outage activities with on line condition monitoring solutions, primarily the periodic verification of MOV functionality discussed in USNRC Generic Letter 96.05. This regulation requires that MOV age related performance degradations are properly identified and accounted for, causing utilities to have to retest valves periodically for the duration of the plants operating license. AECL designed CANDU reactors have a world class performance and safety record, with typical average annual capacity factors of 90%. The CANDU reactor design has the ability to refuel on line, as a result (a) it can be a challenge scheduling all required valve testing into limited duration outage work windows, (b) at multi unit sites, Unit 0 valves can be difficult to test because they are rarely ever out of service, (c) deuterium-oxide (heavy water) moderator is expensive to manufacture, as a result, effective through valve leakage monitoring is essential. These three factors alone make CANDU sites the most suitable candidates for on line valve monitoring systems. Nuclear industry regulations have been instrumental in the development of 'at the valve' diagnostic systems, but diagnostic testing has not typically been utilized to the same degree in other less regulated industries. However, that trend is changing, and the move toward valve diagnostics and condition monitoring has moved fastest in the offshore oil and gas industry on the Norwegian side of the North Sea. The Ormen Lange plant, located on Nyhamna Island on the west coast of Norway, operated by Shell, is one of the worlds most advanced gas processing plants. A stated maintenance goal for the plant is that 70% of the maintenance budget and spend should be based on the results of on line condition monitoring, utilizing monitoring systems equipped with switch sensing, strain gages, hydraulic and pneumatic pressure transducers and acoustic leakage

    The web service DNATCO (dnatco.org) classifies local conformations of DNA molecules beyond their traditional sorting to A, B and Z DNA forms. DNATCO provides an interface to robust algorithms assigning conformation classes called NTC: to dinucleotides extracted from DNA-containing structures uploaded in PDB format version 3.1 or above. The assigned dinucleotide NTC: classes are further grouped into DNA structural alphabet NTA: , to the best of our knowledge the first DNA structural alphabet. The results are presented at two levels: in the form of user friendly visualization and analysis of the assignment, and in the form of a downloadable, more detailed table for further analysis offline. The website is free and open to all users and there is no login requirement. PMID:27150812

    Many scientific domains, specifically in the geosciences, rely on physical samples as basic elements for study and experimentation. Samples are collected to analyze properties of natural materials and features that are key to our knowledge of Earth's dynamical systems and evolution, and to preserve a record of our environment over time. Huge volumes of samples have been acquired over decades or even centuries and stored in a large number and variety of institutions including museums, universities and colleges, state geological surveys, federal agencies, and industry. All of these collections represent highly valuable, often irreplaceable records of nature that need to be accessible so that they can be re-used in future research and for educational purposes. Many sample repositories are keen to use cyberinfrastructure capabilities to enhance access to their collections on the internet and to support and streamline collection management (accessioning of new samples, labeling, handling sample requests, etc.), but encounter substantial challenges and barriers to integrate digital sample management into their daily routine. They lack the resources (staff, funding) and infrastructure (hardware, software, IT support) to develop and operate web-enabled databases, to migrate analog sample records into digital data management systems, and to transfer paper- or spreadsheet-based workflows to electronic systems. Use of commercial software is often not an option as it incurs high costs for licenses, requires IT expertise for installation and maintenance, and often does not match the needs of the smaller repositories, being designed for large museums or different types of collections (art, archeological, biological). Geosamples.org is an alliance of sample repositories (academic, US federal and state surveys, industry) and data facilities that aims to develop a cyberinfrastructure that will dramatically advance access to physical samples for the research community, government

    Seamounts are important to research and education in many scientific fields, providing a wide range of data on physical, chemical, biological and geological processes. In order to make a diverse set of seamount data accessible we have developed the Seamount Catalog in EarthRef.org, available through the http://earthref.org/databases/SC/. The primary goal of the Seamount Catalog is to provide access to digital data files on a large assortment of interdisciplinary seamount research. The catalog can be searched at a variety of ability or expert levels allowing it to be used from basic education to advanced research. Each seamount is described in terms of its location, height, volume, elongation, azimuth, irregularity, rifts, morphological classification and relation to other features. GEBCO (General Bathymetric Chart of the Ocean) gazetteer data (2002; 2003) is included in the database in order to provide information on the history, discovery and names of the seamounts. Screen-optimized bathymetry maps, grid files and the original multibeam data files are available for online viewing with higher resolution downloadable versions (AI, PS, PDF) also offered. The data files for each seamount include a map made from the multibeam data only, a map made from Smith and Sandwell's (1996) predicted bathymetry, a merged map incorporating both data sets, and a map showing the differences between the two data sets. We are working towards expanding the Seamount Catalog by integrating bathymetry data from various sources, developing and linking disciplinary reference models, and integrating information from multiple disciplines and from the literature. We hope to create a data integrative environment that provides access to seamount data and the tools needed for working with that data.

    The data.oceandrilling.org web application applies Linked Open Data (LOD) patterns to expose Deep Sea Drilling Project (DSDP), Ocean Drilling Program (ODP) and Integrated Ocean Drilling Program (IODP) data. Ocean drilling data is represented in a rich range of data formats: high resolution images, file based data sets and sample based data. This richness of data types has been well met by semantic approaches and will be demonstrated. Data has been extracted from CSV, HTML and RDBMS through custom software and existing packages for loading into a SPARQL 1.1 compliant triple store. Practices have been developed to streamline the maintenance of the RDF graphs and properly expose them using LOD approaches like VoID and HTML embedded structured data. Custom and existing vocabularies are used to allow semantic relations between resources. Use of the W3c draft RDF Data Cube Vocabulary and other approaches for encoding time scales, taxonomic fossil data and other graphs will be shown. A software layer written in Google Go mediates the RDF to web pipeline. The approach used is general and can be applied to other similar environments like node.js or Python Twisted. To facilitate communication user interface software libraries such as D3 and packages such as S2S and LodLive have been used. Additionally OpenSearch API's, structured data in HTML and SPARQL endpoints provide various access methods for applications. The data.oceandrilling.org is not viewed as a web site but as an application that communicate with a range of clients. This approach helps guide the development more along software practices than along web site authoring approaches.

  2. Fluid-metapelite interaction in an ultramafic mélange: implications for mass transfer along the slab-mantle interface in subduction zones

    Mori, Yasushi; Shigeno, Miki; Nishiyama, Tadao

    2014-12-01

    The slab-mantle interface in subduction zones is a site of tectonic mixing of crustal and mantle rocks. It is the interface for fluid flow of slab-derived components into the mantle wedge. To assess the fluid-rock interaction along the slab-mantle interface, we studied the bleaching of pelitic schist in an ultramafic mélange. The Nishisonogi metamorphic rocks in Kyushu, Japan, comprise ultramafic mélanges intercalated with epidote-blueschist facies schists. The ultramafic mélange consists of tectonic blocks of various lithologies and a matrix of chlorite-actinolite schist and serpentinite. Along the contact with the mélange matrix, pelitic schist blocks are bleached mainly due to the modal increase of albite and the consumption of carbonaceous material. The bleaching is probably attributed to infiltration of Na-rich external fluid from the mélange matrix. Mass balance analysis indicates losses of C, Rb, K2O, Ba, Pb, and SiO2 from the bleached pelitic schist, although Al2O3, TiO2, Sc, Y, Zr, Nb, La, Ce, and Nd remain immobile. This suggests fractionation of large-ion lithophile elements (LILE) and Pb from the high-field-strength elements and rare earth elements during the bleaching. If this ultramafic mélange is analogous to the slab-mantle interface, similar infiltration metasomatism will promote liberation of C, Si, LILE, and Pb from subducting metapelites and enhance metasomatism of the mantle wedge.

    With the rising awareness of a healthy lifestyle, natural functional foods have gained much interest as promising alternatives to synthetic functional drugs. Recently, wild Agaricus bisporus (Lange) Sing. Chaidam has been found and artificially cultivated for its thick fresh body and excellent taste, with its antioxidant and anti-hypoxic abilities unknown.

    Full Text Available With the rising awareness of a healthy lifestyle, natural functional foods have gained much interest as promising alternatives to synthetic functional drugs. Recently, wild Agaricus bisporus (Lange Sing. Chaidam has been found and artificially cultivated for its thick fresh body and excellent taste, with its antioxidant and anti-hypoxic abilities unknown. In this work, the antioxidant potential of its methanolic, 55% ethanolic, aqueous extracts and crude polysaccharide was evaluated in different systems. The results showed that polysaccharide was the most effective in scavenging ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH and hydroxyl radicals, metal chelating activity and reducing power, with EC50 values of 0.02, 2.79, 1.29, and 1.82 mg/mL, respectively.

  7. Unraveling the polymetamorphic history of garnet-bearing metabasites: Insights from the North Motagua Mélange (Guatemala Suture Zone)

    2014-12-01

    The Guatemala Suture Zone is the fault-bound region in central Guatemala that contains the present North American-Caribbean plate boundary. This major composite geotectonic unit contains a variety of ophiolites, serpentinite mélanges, and metavolcano-sedimentary sequences along with high-grade schists, gneisses, low-grade metasediments and metagranites thrusted north and south of the active Motagua fault system (MFS). The North Motagua Mélange (NMM) outcrops north of the MFS and testifies the emplacement of exhumed subduction assemblages along a collisional tectonic setting. The NMM is composed of a serpentinite-matrix mélange that contains blocks of metabasites (subgreenschist facies metabasalt, grt-blueschist, eclogite, grt-amphibolite), vein-related rocks (jadeitite, omphacitite, albitite, mica-rock), and metatrondhjemites. Our new detailed petrographic and thermobarometric study on the garnet-bearing metabasites reveals a complex polymetamorphic history with multiple tectonic events. Eclogites show a classical clockwise PT path composed of (a) prograde blueschist/eclogite facies within garnet cores, (b) eclogite facies metamorphic peak at ~1.7 GPa and 620°C, (c) post-peak blueschist facies, (d) amphibolite facies overprint, and (e) late stage greenschist facies. Two types of garnet amphibolite blocks can be found, the first consist of (a) a relict eclogite facies peak at ~1.3 GPa and 550°C only preserved within anhedral garnet cores, and (b) surrounded by a post-peak amphibolite facies. In contrast, the second type displays a prograde amphibolite facies at 0.6-1.1 GPa and 400-650°C. The eclogites metamorphic peak suggests formation in a normal subduction zone at ~60 km depth, a subsequent exhumation to the middle section of the subduction channel (~35 km), and a later metamorphic reworking at lower P and higher T before its final exhumation. The first type of garnet amphibolite shows a similar trajectory as the eclogites but at warmer conditions. In

    The Exoplanet Orbit Database (EOD) compiles orbital, transit, host star, and other parameters of robustly detected exoplanets reported in the peer-reviewed literature. The EOD can be navigated through the Exoplanet Data Explorer (EDE) Plotter and Table, available on the World Wide Web at exoplanets.org. The EOD contains data for 1492 confirmed exoplanets as of July 2014. The EOD descends from a table in Butler et al.

    2005-01-11

    Comparative genomics provides the means to demarcate functional regions in anonymous DNA sequences. The successful application of this method to identifying novel genes is currently shifting to deciphering the noncoding encryption of gene regulation across genomes. To facilitate the use of comparative genomics to practical applications in genetics and genomics we have developed several analytical and visualization tools for the analysis of arbitrary sequences and whole genomes. These tools include two alignment tools: zPicture and Mulan; a phylogenetic shadowing tool: eShadow for identifying lineage- and species-specific functional elements; two evolutionary conserved transcription factor analysis tools: rVista and multiTF; a tool for extracting cis-regulatory modules governing the expression of co-regulated genes, CREME; and a dynamic portal to multiple vertebrate and invertebrate genome alignments, the ECR Browser. Here we briefly describe each one of these tools and provide specific examples on their practical applications. All the tools are publicly available at the http://www.dcode.org/ web site.

    2015-04-21

    Available biomedical ontologies and knowledge bases currently lack formal and standards-based interconnections between disease, disease vector, and drug treatment vocabularies. The PNNL Medical Linked Dataset (PNNL-MLD) addresses this gap. This paper describes the PNNL-MLD, which provides a unified vocabulary and dataset of drug, disease, side effect, and vector transmission background information. Currently, the PNNL-MLD combines and curates data from the following research projects: DrugBank, DailyMed, Diseasome, DisGeNet, Wikipedia Infobox, Sider, and PharmGKB. The main outcomes of this effort are a dataset aligned to Schema.org, including a parsing framework, and extensible hooks ready for integration with selected medical ontologies. The PNNL-MLD enables researchers more quickly and easily to query distinct datasets. Future extensions to the PNNL-MLD will include Traditional Chinese Medicine, broader interlinks across genetic structures, a larger thesaurus of synonyms and hypernyms, explicit coding of diseases and drugs across research systems, and incorporating vector-borne transmission vocabularies.

    Full Text Available In order to identify new ways to prevent, diagnose and treat diseases, biobanks systematically collect samples of human tissues and population-wide data on health and lifestyle. Efficient access to population biobank data and to biomaterial is crucial for development and marketing of new pharmaceutical products, especially in the area of personalised medicine. However, such access is hindered by legal and ethical constraints, and by the huge semantic diversity across different biobanks. To address these challenges, we have developed SAIL, a sophisticated metaportal for biobank data annotation across different collections and repositories, harmonised to allow cross-biobank searchability, while preserving the anonymity and privacy of the underlying data such that legal and ethical requirements are met. We describe the technological architecture and design of SAIL that allows us to meet these pressing challenges, and give an overview of the current functionality of the application. SAIL is available online at sail.simbioms.org, and it currently contains around 200 000 samples from 14 collections.

    Full Text Available BioCyc.org is a genome and metabolic pathway web portal covering 5500 organisms, including Homo sapiens, Arabidopsis thaliana, Saccharomyces cerevisiae and Escherichia coli. These organism-specific databases have undergone variable degrees of curation. The EcoCyc (Escherichia coli Encyclopedia database is the most highly curated; its contents have been derived from 27,000 publications. The MetaCyc (Metabolic Encyclopedia database within BioCyc is a “universal” metabolic database that describes pathways, reactions, enzymes and metabolites from all domains of life. Metabolic pathways provide an organizing framework for analyzing metabolomics data, and the BioCyc website provides computational operations for metabolomics data that include metabolite search and translation of metabolite identifiers across multiple metabolite databases. The site allows researchers to store and manipulate metabolite lists using a facility called SmartTables, which supports metabolite enrichment analysis. That analysis operation identifies metabolite sets that are statistically over-represented for the substrates of specific metabolic pathways. BioCyc also enables visualization of metabolomics data on individual pathway diagrams and on the organism-specific metabolic map diagrams that are available for every BioCyc organism. Most of these operations are available both interactively and as programmatic web services.

    1998-01-01

    This introduction to the recent exciting developments in the applications of model theory to algebraic geometry, illustrated by E. Hrushovski's model-theoretic proof of the geometric Mordell-Lang Conjecture starts from very basic background and works up to the detailed exposition of Hrushovski's proof, explaining the necessary tools and results from stability theory on the way. The first chapter is an informal introduction to model theory itself, making the book accessible (with a little effort) to readers with no previous knowledge of model theory. The authors have collaborated closely to achieve a coherent and self- contained presentation, whereby the completeness of exposition of the chapters varies according to the existence of other good references, but comments and examples are always provided to give the reader some intuitive understanding of the subject.

    It is a major challenge to bring science and technology to the public at large and more particular to young people. This is even more true for marine sciences, due to the very nature of the study field and the fact that the underwater world is difficult to experience and communicate. Therefore it is not surprising that in Europe there are only few examples of marine educational projects that try to go beyond the ‘observe and describe' approach. In 2004 SHE Consultancy, the Flanders Marine Institute VLIZ and DAB Vloot developed a first Belgian e-learning programme dedicated to oceans and seas, with the support of the Flemish government ("Action plan Science Communication"). This programme ‘Expedition Zeeleeuw' (www.expeditiezeeleeuw.be), ran from 2005 till 2007 and challenged some 3000 Flemish students of 16-18 years old all over Flanders to find creative solutions for 10 major marine issues at the Belgian coast. The class that could convince the jury to have discovered the most creative and intelligent solutions, wan a one-week scientific expedition at sea on board the vessel Zeeleeuw. As a successor to ‘Expedition Zeeleeuw', a new e-learning project on marine science was developed in 2007: ‘Planeet Zee' i.e. ‘Planet Ocean' (www.planeetzee.org; info via info@planeetzee.org + demo-site in English available at www.planetocean.eu). The new marine and coastal e-learning project is presented as a virtual sailing trip on the Atlantic Ocean. It follows the adventures of two youngsters "borrowing" the yacht of their father and getting into trouble on the open ocean. On this journey they face 21 problems (eg. out of food, drinking water or fuel, fear for whales, Bermuda triangle, tsunami's etc… ), each of them introduced by a short movie clip. When they realize they can not solve the problem, they ask for radio help and - what a surprise! - get interesting answers from the Zeeleeuw research vessel and its 21 marine scientists on board, that appears to be in the

    Full Text Available The ability to transmit, organize, and query information digitally has brought with it the challenge of how to best use this power to facilitate scientific inquiry. Today, few information systems are able to provide detailed answers to complex questions about neuroscience that account for multiple spatial scales, and which cross the boundaries of diverse parts of the nervous system such as molecules, cellular parts, cells, circuits, systems and tissues. As a result, investigators still primarily seek answers to their questions in an increasingly densely populated collection of articles in the literature, each of which must be digested individually. If it were easier to search a knowledge base that was structured to answer neuroscience questions, such a system would enable questions to be answered in seconds that would otherwise require hours of literature review.In this article, we describe NeuroLex.org, a wiki-based website and knowledge management system. Its goal is to bring neurobiological knowledge into a framework that allows neuroscientists to review the concepts of neuroscience, with an emphasis on multiscale descriptions of the parts of nervous systems, aggregate their understanding with that of other scientists, link them to data sources and descriptions of important concepts in neuroscience, and expose parts that are still controversial or missing. To date, the site is tracking ~25,000 unique neuroanatomical parts and concepts in neurobiology spanning experimental techniques, behavioral paradigms, anatomical nomenclature, genes, proteins and molecules. Here we show how the structuring of information about these anatomical parts in the nervous system can be reused to answer multiple neuroscience questions, such as displaying all known GABAergic neurons aggregated in NeuroLex or displaying all brain regions that are known within NeuroLex to send axons into the cerebellar cortex.

    The Xiukang Mélange of the Yarlung-Zangbo suture zone in south Tibet documents low efficiency of accretion along the southern active margin of Asia during Cretaceous Neotethyan subduction, followed by final development during the early Paleogene stages of the India-Asia collision. Here we investigate four transverses in the Xigaze area (Jiding, Cuola Pass, Riwuqi and Saga), inquiry the composition in each transverse, and present integrated petrologic, U-Pb detrital-zircon geochronology and Hf isotope data on sandstone blocks. In fault contact with the Yarlung-Zangbo Ophiolite to the north and the Tethyan Himalaya to the south, the Xiukang mélange can be divided into three types: serpentinite-matrix mélange composed by broken Yarlung-Zangbo Ophiolite, thrust-sheets consisting mainly chert, quartzose or limestone sheets(>100m) with little intervening marix, and mudstone-matrix mélange displaying typical blocks-in-matrix texture. While serpentinite-matrix mélange is exposed adjacent to the ophiolite, distributions of thrust-sheets and blocks in mudstone-matrix mélange show along-strike diversities. For example, Jiding transverse is dominant by chert sheets and basalt blocks with scarcely sandstone blocks, while Cuola Pass and Saga transverses expose large amounts of limestone/quartzarenite sheets in the north and volcaniclastic blocks in the south. However, turbidite sheets and volcaniclastic blocks are outcropped in the north Riwuqi transverse with quartzarenite blocks preserved in the south. Three groups of sandstone blocks/sheets with different provenance and depositional setting are distinguished by their petrographic, geochronological and isotopic fingerprints. Sheets of turbiditic quartzarenite originally sourced from the Indian continent were deposited in pre-Cretaceous time on the northernmost edge of the Indian passive margin and eventually involved into the mélange at the early stage of the India-Asia collision.

    In the March issue of the Journal in 2012, we reported on a girl with Langer-Giedion syndrome (LGS) phenotype and a 7.5 Mb interstitial deletion at 8q23.3q24.13, encompassing the EXT1, but not the TRPS1 gene. Recent discoveries have shown that heterozygous intragenic mutations or contiguous gene deletions including the RAD21 gene, which is located downstream of the TRPS1 gene, are the cause of Cornelia de Lange syndrome-4. Considering that the interstitial deletion in our patient included the RAD21 and 30 other RefSeq genes, we would like to suggest a revision of the diagnosis reported in our previous paper and compare our patient to other reported patients with Cornelia de Lange syndrome-4 caused by heterozygous deletions of chromosome 8q24. © 2015 Wiley Periodicals, Inc.

    Cornelia de Lange syndrome (CdLS) and KBG syndrome are two distinct developmental pathologies sharing common features such as intellectual disability, psychomotor delay, and some craniofacial and limb abnormalities. Mutations in one of the five genes NIPBL, SMC1A, SMC3, HDAC8 or RAD21, were identified in at least 70% of the patients with CdLS. Consequently, additional causative genes, either unknown or responsible of partially merging entities, possibly account for the remaining 30% of the patients. In contrast, KBG has only been associated with mutations in ANKRD11. By exome sequencing we could identify heterozygous loss-of-function mutations in ANKRD11 in two patients with the clinical diagnosis of CdLS. Both patients show features reminiscent of CdLS such as characteristic facies as well as a small head circumference which is not described for KBG syndrome. Patient A, who carries the mutation in a mosaic state, is a 4-year-old girl with features reminiscent of CdLS. Patient B, a 15-year-old boy, shows a complex phenotype which resembled CdLS during infancy, but has developed to a more KBG overlapping phenotype during childhood. These findings point out the importance of screening ANKRD11 in young CdLS patients who were found to be negative for mutations in the five known CdLS genes. PMID:25652421

    Cornelia de Lange Syndrome (CdLS) is a multi-organ system birth defects disorder linked, in at least half of cases, to heterozygous mutations in the NIPBL gene. In animals and fungi, orthologs of NIPBL regulate cohesin, a complex of proteins that is essential for chromosome cohesion and is also implicated in DNA repair and transcriptional regulation. Mice heterozygous for a gene-trap mutation in Nipbl were produced and exhibited defects characteristic of CdLS, including small size, craniofacial anomalies, microbrachycephaly, heart defects, hearing abnormalities, delayed bone maturation, reduced body fat, behavioral disturbances, and high mortality (75-80%) during the first weeks of life. These phenotypes arose despite a decrease in Nipbl transcript levels of only approximately 30%, implying extreme sensitivity of development to small changes in Nipbl activity. Gene expression profiling demonstrated that Nipbl deficiency leads to modest but significant transcriptional dysregulation of many genes. Expression changes at the protocadherin beta (Pcdhb) locus, as well as at other loci, support the view that NIPBL influences long-range chromosomal regulatory interactions. In addition, evidence is presented that reduced expression of genes involved in adipogenic differentiation may underlie the low amounts of body fat observed both in Nipbl+/- mice and in individuals with CdLS.

    Full Text Available Cornelia de Lange syndrome (CdLS is a congenital developmental disorder characterized by distinctive craniofacial features, growth retardation, cognitive impairment, limb defects, hirsutism, and multisystem involvement. Mutations in five genes encoding structural components (SMC1A, SMC3, RAD21 or functionally associated factors (NIPBL, HDAC8 of the cohesin complex have been found in patients with CdLS. In about 60% of the patients, mutations in NIPBL could be identified. Interestingly, 17% of them are predicted to change normal splicing, however, detailed molecular investigations are often missing. Here, we report the first systematic study of the physiological splicing of the NIPBL gene, that would reveal the identification of four new splicing isoforms ΔE10, ΔE12, ΔE33,34, and B’. Furthermore, we have investigated nine mutations affecting splice-sites in the NIPBL gene identified in twelve CdLS patients. All mutations have been examined on the DNA and RNA level, as well as by in silico analyses. Although patients with mutations affecting NIPBL splicing show a broad clinical variability, the more severe phenotypes seem to be associated with aberrant transcripts resulting in a shift of the reading frame.

  15. PAS domain of the deduced Org35 protein mediates the interaction with NifA

    NifA in Azospirillum brasilense plays a key role in regulating the synthesis of nitrogenase in response to ammonia and oxygen available. Recently,our laboratory has identified four clones, whose gene prodcuts interact with NifA, from A. brasilense Sp7genomic libraries by using the yeast two-hybrid system with NifA as bait. We are interested in clone S35,one of the four clones, because it contains a PAS-domain coding region. The entire open reading frame (ORF) for the PAS domain-containing protein was isolated and designated as org35 here. org35gene is 2211-bp long and encodes a protein of 736aa with a predicted molecular weight of about 78.4 kD.The predicted amino acid sequence of org35 has similarity to some two-component sensor kinase/response regulator hybrids of bacteria. Structural analyses showed that Org35 comprises at least three discrete conserved domains: the N-terminal PAS, the central histidine protein kinase (HPK) and the C-terminal response regulator (RR). The PAS domain of the deduced Org35 protein was found to interact directly with NifA, but the central HPK and the C-terminal RR domains of Org35 were not. These results indicated that interaction between NifA and Org35 was mediated by PAS domain.

  18. Magmatic origin of low-T mafic blueschist and greenstone blocks from the Franciscan mélange, San Simeon, California

    Science.gov (United States)

    Ukar, Estibalitz; Cloos, Mark

    2015-08-01

    The Franciscan mélange exposure near San Simeon contains abundant greenstone and minor blueschist blocks that were tectonically boudinaged while encased in the shale-matrix. Tectonic deformation of the blueschists is evident from variable amounts of cataclastic flow along their margins and in pinched tails. Major, trace, and rare earth elemental analyses indicate that blueschist and greenstone blocks in this area of the mélange were derived from sources with MORB-like composition along with some having trace element and REE patterns similar to OIB compositions. Most blocks are low LREE basalts that probably formed in an open ocean ridge setting, but some blocks have high LREE contents similar to off-axis seamounts. Linear trends of incompatible elements for both blueschist and greenstone blocks indicate that both lithologies were probably derived from a similar, variably fractionated, tholeiitic magma. Blueschist blocks with sodic amphibole + lawsonite ± epidote were pervasively recrystallized at 300-350 °C and foliated during ductile deformation that included folding. Their protolith can only be identified as mafic. A few blocks contain very small amounts of metasedimentary materials indicating some were probably seafloor basalts, but some may have been diabase or even gabbro. Where interlayered sediment was present, the mafic protolith was enriched in K, Rb, and Na. Greenstones, on the other hand, contain abundant pseudomorphic evidence of magmatic textures. Alteration to albite, chlorite and pumpellyite at temperatures of 100-200 °C is intense, especially in cataclastic margins and pinched tails. Some of the basaltic greenstones have attached radiolarian chert, and a few have relict diabasic textures. The mafic blueschists and greenstones in the mélange near San Simeon are probably fragments from the uppermost part of the Farallon plate. The blueschists may be mostly mafic slabs uprooted from the subducting crust, underplated to the base of the North

  19. Remnants of a hyperextended passive margin in a Caledonian mélange unit below the Jotun nappe, B\\overdalen, Central-south Norway

    The Scandinavian Caledonides have been long studied, yet their ever unfolding complexity renders them far from being fully understood. It has been recognized that the Caledonian Allochthons have neither a linear nor straightforward along-strike relationship (Corfu et al. 2014). A mélange unit has been recently identified as a separate tectonic unit (Andersen et al. 2012). This unit is structurally positioned below crystalline nappes previously assigned to the Middle Allochthon. The mélange comprises meta-sediments and minor meta-basalt/gabbro, but most intriguingly, numerous solitary meta-peridotites. These occur as 'Alpine type' meta-peridotites, serpentinites, soapstones and detrital serpentinites. We present results of a field study of the mélange in the B\\overdalen area, structurally below the Jotun nappe, and suggest that this provides further evidence that the regional mélange unit was formed in a hyperextended passive margin. The meta-peridotites represent exhumed serpentinized mantle and are intimately associated with meta-sediments. The sediments are garnetiferous chlorite-muscovite schists, graphitic schists, phyllites, amphibolites, meta-sandstones as well as quartzite-pebble dominated conglomerates. It is suggested that this highly heterogeneous unit formed during the early stages of rifting and hyperextension along the Baltican passive margin. Characteristics of the detrital peridotites suggests that serpentinite-talc protrusions may have formed islands. The processes involved are observed on modern margins where the best-studied example is the Iberia-Newfoundland passive margin. Work in present-day margins (mostly seismic reflection data) elucidate the large-scale structure of hyperextended margins, while studies of ancient exposed examples in mountain belts provide insight into the lithology, geochemistry and details of these margins. The widespread distribution of hyperextended margins in modern margins and the increasing number of recognizable

    Given the clinical complexities of Cornelia de Lange Syndrome (CdLS), the Center for CdLS and Related Diagnoses at The Children's Hospital of Philadelphia (CHOP) and The Multidisciplinary Clinic for Adolescents and Adults at Greater Baltimore Medical Center (GBMC) were established to develop a comprehensive approach to clinical management and research issues relevant to CdLS. Little work has been done to evaluate the general utility of a multispecialty approach to patient care. Previous research demonstrates several advantages and disadvantages of multispecialty care. This research aims to better understand the benefits and limitations of a multidisciplinary clinic setting for individuals with CdLS and related diagnoses. Parents of children with CdLS and related diagnoses who have visited a multidisciplinary clinic (N = 52) and who have not visited a multidisciplinary clinic (N = 69) were surveyed to investigate their attitudes. About 90.0% of multispecialty clinic attendees indicated a preference for multidisciplinary care. However, some respondents cited a need for additional clinic services including more opportunity to meet with other specialists (N = 20), such as behavioral health, and increased information about research studies (N = 15). Travel distance and expenses often prevented families' multidisciplinary clinic attendance (N = 41 and N = 35, respectively). Despite identified limitations, these findings contribute to the evidence demonstrating the utility of a multispecialty approach to patient care. This approach ultimately has the potential to not just improve healthcare for individuals with CdLS but for those with medically complex diagnoses in general. © 2016 Wiley Periodicals, Inc.

    577 air dust samples have been collected with two kinds of air samplers (2-SFU, 1-ASP) on every Wednesday and Sunday for 24 hours at both of monitoring stations (Lang - Hanoi and Lucnam - Bacgiang). PM(2.5), PM(2.5-10), PM(10) and BC concentrations in 452 air dust samples have been determined. 9032 data have been analyzed with many of different multi-elements analytical techniques (IC: 264 samples x 9 ions, PIXE: 388 samples x 15 elements, XRF: 48 samples x 8 elements, LR: 452 samples x 1 element). Over 6000 of meteorological parameters (T, Rain, WS, WD, RH...) have been collected and processed.Variations and levels of air dust concentrations and BC in Hanoi from 1998 to 2002 have been studied. PM(2.5), PM(2.5-10), PM(10) and BC concentrations and BC obviously periodically vary. They reach maximum in the winter season, especially in December and January, sometimes they reached 300-400 μg.m-3, They reach minimum in the summer season, sometimes they went down 10 μg.m-3 on rainy days. These variations were affected by meteorological parameters. PM(2.5), PM(10) daily average concentrations in Hanoi are greater than the American air standards (PM(2.5): 65 μg.m-3, PM(10): 150 μg.m-3) in many days and their yearly average concentrations are also far exceeded. Air dust pollution levels in Hanoi are higher than in developed countries and even countries in the region. BC (5.9 μg.m-3) concentration and Pb (0.11 μg.m-3) are also higher than in many countries.

    There is an abundance of information in the literature on patient experiences with Internet support groups (ISGs). However, studies exploring these experiences in a rare disease population are scarce, even though these families are often at a disadvantage for resources, reliable information, and support. The aim of the current study was to explore the experiences with ISGs for parents of children with Cornelia de Lange syndrome (CdLS), a rare genetic diagnosis, in order to better understand the impact on emotional support and their child's medical care. Focus groups were conducted to inform the design of a large-scale internet survey. The survey asked parents closed- and open-ended questions regarding experiences with ISGs, with a focus on the psychosocial, medical, and logistical aspects. The survey found that 141/170 (82.6%) respondents have visited an Internet-based support group to find support or information about their child's CdLS diagnosis. The majority of respondents (71.7%) reported that ISGs have been helpful in finding emotional support, with the most common areas impacted as a result of ISG participation being behavior toward their children and family dynamic. Regarding medical care, most respondents (63.9%) reported that ISGs have been helpful in finding medical information and support, with the most commonly impacted areas of their child's care including day-to-day management, diet, therapy interventions, and healthcare providers. These findings provide a greater understanding of the role of Internet networking in healthcare and may inform future approaches to medical care and psychosocial support for rare, complex genetic diagnoses. © 2016 Wiley Periodicals, Inc.

    Full Text Available This work reviews recent progress in the application of continuous thermodynamics towards calculation of phase equilibria in natural-gas mixtures. In such mixtures, there may be too many components to identify each component individually. Continuous thermodynamics provides a theoretical framework for representing the composition of a portion of the natural-gas mixture by a continuous distribution function. Advances in continuous thermodynamics are discussed in three areas :(1 Characterization and representation of composition in a many-component mixture(2 Development and application of molecular-thermodynamic models for continuous mixtures, and(3 Implementation of efficient numerical techniques for solving material-balance and phase-equilibrium equations. While continuous thermodynamics provides a useful tool for calculation of phase equilibria in natural-gas mixtures, successful implementation requires better chemical-analytical characterization methods. Further, improved semi-theoretical techniques must be developed to relate experimental characterization information to physically significant parameters in molecular-thermodynamic models. Ce travail examine les récents développements de l'application de la thermodynamique continue au calcul des équilibres de phases de mélanges de gaz naturel. Dans ces mélanges, les composants sont souvent en trop grand nombre pour qu'on puisse les identifier individuellement.

    2004-10-04

    Research at the world's accelerator- (storage-ring and linac) based light sources is one of the most dynamic and rapidly growing fields of science. It frequently results in direct benefits to society, thereby demonstrating the value of the research with very concrete examples, but this is not widely understood or appreciated outside of the immediate user community. Our growing group of light source communicators from facilities in Europe, Asia, and the Americas, inspired by the Interactions.org Web site created by high-energy (elementary-particle)physics communicators, concluded that a light source community Web site (lightsources.org) would be the best tool for establishing effective collaboration between the communications offices of the world's light sources and to maximize the impact of our efforts. We envision lightsources.org to serve as a one-stop-shopping site for information about all aspects of light sources and the research they make possible. Audiences to be served include science communicators, the press, policymakers, the light source community, the wider scientific community, the science-interested public, and students and educators. Our proposal has been sent to the world's light source facility directors by J. Murray Gibson (APS) and William G. Stirling (ESRF). As a result,light sources.org is now being supported by a growing list of facilities from Europe, North America, and Asia. We hope to launch lightsources.org before the end of 2004.

  10. Characteristics of ophiolite-related metamorphic rocks in the Beysehir ophiolitic mélange (Central Taurides, Turkey), deduced from whole rock and mineral chemistry

    Small outcrops of the metamorphic rocks of the Beysehir ophiolite appear to the west of Gencek and to the south of Durak (South of Beysehir Lake) in the Central Tauride Belt in Turkey. Amphibolitic rocks in the ophiolitic mélange have an igneous origin. Protoliths of these rocks were probably alkali basalts, gabbros or some ultramafic cumulates, such as pyroxenite. The amphibolites of the Beysehir Ophiolite can be divided into four groups: (1) amphibole+garnet+plagioclase±epidote (as secondary minerals)±opaque such as ilmenite±accessory minerals such as sphene and apatite; (2) amphibole+pyroxene+plagioclase±epidote±accessory minerals such as sphene, apatite±chlorite, calcite (as secondary mineral); (3) amphibole±plagioclase±opaque±accessory minerals; (4) amphibole+plagioclase±epidote±biotite and muscovite±opaque±accessory minerals. These metamorphic rocks show mainly granoblastic, grano-nematoblastic, porphyroblastic and/or poikiloblastic textures. All amphiboles in the amphibolites are calcic and cluster in the range from magnesio-hastingsite, pargasite to actinolite. Amphibole compositions are characterized by SiO 2=(38.02-54.3%), Al 2O 3=(1.5-12.8), FeO=(10.03-14.67%), K 2O=(0.2-1.8%), MgO=(5.5-15.7), Mg*=(0.3-0.8). The amphibolites show an alkaline to subalkaline character. However, the primitive mantle normalized incompatible trace element diagram shows close similarity with the typical ocean island basalt (OIB) pattern. The Rock/Chondrite normalized REE diagram of the amphibolites also confirms their OIB signature. Tectonomagmatic discrimination diagrams based on the immobile trace elements suggest a mostly within-plate alkali basalt (WPB) environment. Beysehir ophiolitic mélange contains amphibolites from ophiolite-related metamorphic rocks, but the matrix of the Beysehir ophiolitic mélange is not metamorphosed. Blocks of metamorphic rocks and the ophiolitic rocks may have been incorporated into the ophiolitic mélange in an oceanic

    The economical efficiency of the application of an increasing hydrogel dose in bispore mushrooms (Agaricus bisporus (Lange) Sing. Imbach SYLVAN 737) has been experimented in controlled weather conditions. It was found that the application of a 50 and 150 g•m-2 hydrogel dose is not economically proved due to the lack of harvest significant increase. In the cultivation of this particular variety of mushrooms, the optimal hydrogel dose should not be 100 g•m-2 of subsoil.

    The microstructures of the mantle tectonites in the Zunhua Neoarchean ophiolitic mélange are mainly coarse-mosaic structures with locally interstitial impregnated melts. Olivine and orthopyroxene occur as residual porphyroclastic blasts, dynamic recrystallization neoblasts or elongated to be tabular. The podiform chromitites are mostly strongly deformed with the development of pull-apart structure. These microstructures are typical high-temperature plastic deformation in oceanic upper mantle resulting from ocean-floor spreading. Besides the high-temperature plastic deformation, undeformed magmatic intrusions such as undeformed podiform chromitite, dunite and pyroxenite intrusions are also preserved in the mantle tectonite. Structures of high-temperature plastic deformation and intensive magmatic activity prove that the Zunhua ophiolite was formed under fast spreading oceanic ridge, similar to the Oman ophiolite. And the microstructures of country rocks, such as quartz ribbon, core and mantle structure, dynamic recrystallization and mica-fish stucture, etc., were formed during the uplift of ophiolitic mélange from the mid-crust to the upper-crust associated with continental collision.

    Researchers require infrastructures that ensure a maximum of accessibility, stability and reliability to facilitate working with and sharing of research data. Such infrastructures are being increasingly summarized under the term Research Data Repositories (RDR). The project re3data.org-Registry of Research Data Repositories-has begun to index research data repositories in 2012 and offers researchers, funding organizations, libraries and publishers an overview of the heterogeneous research data repository landscape. In July 2013 re3data.org lists 400 research data repositories and counting. 288 of these are described in detail using the re3data.org vocabulary. Information icons help researchers to easily identify an adequate repository for the storage and reuse of their data. This article describes the heterogeneous RDR landscape and presents a typology of institutional, disciplinary, multidisciplinary and project-specific RDR. Further the article outlines the features of re3data.org, and shows how this registry helps to identify appropriate repositories for storage and search of research data. PMID:24223762

    2016-08-01

    This contribution provides an overview of Paleomagnetism.org, an open-source, multi-platform online environment for paleomagnetic data analysis. Paleomagnetism.org provides an interactive environment where paleomagnetic data can be interpreted, evaluated, visualized, and exported. The Paleomagnetism.org application is split in to an interpretation portal, a statistics portal, and a portal for miscellaneous paleomagnetic tools. In the interpretation portal, principle component analysis can be performed on visualized demagnetization diagrams. Interpreted directions and great circles can be combined to find great circle solutions. These directions can be used in the statistics portal, or exported as data and figures. The tools in the statistics portal cover standard Fisher statistics for directions and VGPs, including other statistical parameters used as reliability criteria. Other available tools include an eigenvector approach foldtest, two reversal test including a Monte Carlo simulation on mean directions, and a coordinate bootstrap on the original data. An implementation is included for the detection and correction of inclination shallowing in sediments following TK03.GAD. Finally we provide a module to visualize VGPs and expected paleolatitudes, declinations, and inclinations relative to widely used global apparent polar wander path models in coordinates of major continent-bearing plates. The tools in the miscellaneous portal include a net tectonic rotation (NTR) analysis to restore a body to its paleo-vertical and a bootstrapped oroclinal test using linear regressive techniques, including a modified foldtest around a vertical axis. Paleomagnetism.org provides an integrated approach for researchers to work with visualized (e.g. hemisphere projections, Zijderveld diagrams) paleomagnetic data. The application constructs a custom exportable file that can be shared freely and included in public databases. This exported file contains all data and can later be

    Full Text Available As hortaliças são os alimentos que mais se destacam, em artigos científicos e em jornais, quando se trata de contaminação com agrotóxicos. Isso tem levado ao aumento na demanda por produtos orgânicos por parte dos consumidores. Há, então, a necessidade de se desenvolverem tecnologias que viabilizem esses sistemas, atendendo ao consumidor e melhorando a renda dos agricultores, geralmente de base familiar. A produção de hortaliças em sistema orgânico requer tecnologias que respeitem os processos ecológicos, que promovam o aumento da matéria orgânica do solo e que sejam poupadoras de energia. Neste artigo, são discutidas algumas dessas tecnologias e resultados de pesquisas, com foco em produção de mudas, manejo e adubação do solo, adubação verde, rotação de culturas, consórcio de hortaliças, manejo de plantas espontâneas e manejo de pragas e doenças, que são práticas aprovadas pelas normas para produção orgânica e seguem os princípios agroecológicos, que contribuem para a maior eficiência energética dos sistemas produtivos e, em conjunto, para o necessário desenvolvimento do setor de produção de hortaliças orgânicas com base científica.

  18. A Kind of Optimization Method of Loading Documents in OpenOffice.org

    Science.gov (United States)

    Lan, Yuqing; Li, Li; Zhou, Wenbin

    As a giant in open source community, OpenOffice.org has become the most popular office suite within Linux community. But OpenOffice.org is relatively slow while loading documents. Research shows that the most time consuming part is importing one page of whole document. If there are many pages in a document, the accumulation of time consumed can be astonishing. Therefore, this paper proposes a solution, which has improved the speed of loading documents through asynchronous importing mechanism: a document is not imported as a whole, but only part of the document is imported at first for display, then mechanism in the background is started to asynchronously import the remaining parts, and insert it into the drawing queue of OpenOffice.org for display. In this way, the problem can be solved and users don't have to wait for a long time. Application start-up time testing tool has been used to test the time consumed in loading different pages of documents before and after optimization of OpenOffice.org, then, we adopt the regression theory to analyse the correlation between the page number of documents and the loading time. In addition, visual modeling of the experimental data are acquired with the aid of matlab. An obvious increase in loading speed can be seen after a comparison of the time consumed to load a document before and after the solution is adopted. And then, using Microsoft Office compared with the optimized OpenOffice.org, their loading speeds are almost same. The results of the experiments show the effectiveness of this solution.

  6. Ultra-oxidized rocks in subduction mélanges? Decoupling between oxygen fugacity and oxygen availability in a Mn-rich metasomatic environment

    Science.gov (United States)

    Tumiati, Simone; Godard, Gaston; Martin, Silvana; Malaspina, Nadia; Poli, Stefano

    2015-06-01

    The manganese ore of Praborna (Italian Western Alps) is embedded within a metasedimentary sequence belonging to a subduction mélange equilibrated at high-pressure (HP) conditions (ca. 2 GPa) during the Alpine orogenesis. The pervasive veining of the ore and the growth of "pegmatoid" HP minerals suggest that these Mn-rich rocks strongly interacted with slab-derived fluids during HP metamorphism. These rocks are in textural and chemical equilibrium with the veins and in contact with sulphide- and magnetite-bearing metabasites at the bottom of the sequence. They contain braunite (Mn2+Mn3+6SiO12), quartz, pyroxmangite (Mn2+SiO3), and minor hematite, omphacite, piemontite and spessartine-rich garnet. Sulphides are absent in the Mn-rich rocks, whereas sulphates (barite, celestine) occur together with As- and Sb-oxides and silicates. This rock association provides an excellent natural laboratory to constrain the redox conditions in subducting oceanic slab mélanges at HP and fluid-present conditions. Similarly to Fe-bearing minerals, Mn oxides and silicates can be regarded as natural redox-sensors. A thermodynamic dataset for these Mn-bearing minerals is built, using literature data as well as new thermal expansion parameters for braunite aud pyrolusite, derived from experiments. Based on this dataset and the observed assemblages at Praborna, thermodynamic calculations show that these mélange rocks are characterised by ultra-oxidized conditions (∆FMQ up to + 12.7) if the chemical potential of oxygen (or the oxygen fugacity fO2) is accounted for. On the other hand, if the molar quantity of oxygen is used as the independent state variable to quantify the bulk oxidation state, the ore appears only moderately oxidized and comparable to typical subduction-slab mafic eclogites. Such an apparent contradiction may happen in rock systems whenever oxygen is improperly considered as a perfectly mobile component. In the Earth's mantle, redox reactions take place mainly between

In this study we describe a 23-year-old male patient with intellectual disability, behavioral problems, dysmorphic features, dysphagia, gastroesophageal reflux and skeletal abnormalities....... Cornelia de Lange syndrome (CdLS, OMIM #122470; #300590; #610759; #300882; #614701) was suggested as a differential diagnosis in childhood although he lacked some of the features typical for this disorder. He does not have a mutation in any of the five known CdLS genes (NIPBL, SMC1A, SMC3, HDAC8, RAD21...... spectrum disorder; and CDCA5, which is part of the cohesin pathway, as are all the five known CdLS genes. It is thereforepossible that deletion of CDCA5 may account for some of the CdLS like features of the present case....

    Full Text Available Despite evaluation of large number of agroindustrial wastes for their use as casing material for Agaricus bisporus (Lange Imbach cultivation, scant attention has been given to the importance of biological properties of casing materials. In the present study, an attempt was made to characterize the bacterial flora in casing layer, namely, Farm Yard Manure (FYM and Spent Mushroom Substrate/spent compost (SMS/SC (FYM+SC, 3 : 1 and FYM and Vermi Compost (VC (FYM+VC, 3 : 1, employing partial 16S rDNA sequencing. Available data showed a significant variety of organisms that included Acinetobacter and Pseudomonas of the γ-proteobacteria, that were the most frequently encountered genera. This is the first preliminary report on the microbial diversity of casing soils and demonstrates the presence of Acinetobacter spp. that has not been previously described in casing material.

    La gestion proche de la nature des forêts est de plus en plus préconisée et pratiquée. Cependant, les gestionnaires forestiers ont souvent beaucoup de difficultés à maintenir le mélange d’espèces de tolérance différente à l’ombrage. Si la gestion forestière a généralement réussi à maintenir une production de bois constante, elle a rarement réussi à promouvoir la régénération naturelle d’espèces diversifiées. Dans ces conditions, nous voulions approfondir nos connaissances sur la dynamique des...

  10. Are seasonal calving dynamics forced by buttressing from ice mélange or undercutting by melting? Outcomes from full-Stokes simulations of Store Gletscher, West Greenland

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available We use a full-Stokes 2-D model (Elmer/Ice to investigate the flow and calving dynamics of Store Gletscher, a fast flowing outlet glacier in West Greenland. Based on a new, subgrid-scale implementation of the crevasse depth calving criterion, we perform two sets of simulations; one to identify the primary forcing mechanisms and another to constrain future stability. We find that the mixture of icebergs and sea-ice, known as ice mélange or sikussak, is principally responsible for the observed seasonal advance of the ice front, whereas submarine melting plays a secondary role. Sensitivity analysis demonstrates that the glacier's calving dynamics are sensitive to seasonal perturbation, but are stable on interannual timescales due to the glacier's topographic setting. Our results shed light on the dynamics of calving glaciers while explaining why neighbouring glaciers do not necessarily respond synchronously to changes in atmospheric and oceanic forcing.

  3. BikeMaps.org: a global tool for collision and near miss mapping

    Directory of Open Access Journals (Sweden)

    Trisalyn A Nelson

    2015-03-01

    Full Text Available There are many public health benefits to cycling, such as chronic disease reduction and improved air quality. Real and perceived concerns about safety are primary barriers to new ridership. Due to limited forums for official reporting of cycling incidents, lack of comprehensive data is limiting our ability to study cycling safety and conduct surveillance. Our goal is to introduce BikeMaps.org, a new website developed by the authors for crowd-source mapping of cycling collisions and near misses. BikeMaps.org is a global mapping system that allows citizens to map locations of cycling incidents and report on the nature of the event. Attributes collected are designed for spatial modelling research on predictors of safety and risk, and to aid surveillance and planning. Released in October 2014, within two months the website had more than 14,000 visitors and mapping in 14 countries. Collisions represent 38% of reports (134/356 and near misses 62% (222/356. In our pilot city, Victoria, Canada, citizens mapped data equivalent to about one year of official cycling collision reports within two months via BikeMaps.org. Using report completeness as an indicator, early reports indicate that data are of high quality with 50% being fully attributed and another 10% having only one missing attribute. We are advancing this technology, with the development of a mobile App, improved data visualization, real-time altering of hazard reports, and automated open-source tools for data sharing. Researchers and citizens interested in utilizing the BikeMaps.org technology can get involved by encouraging citizen mapping in their region.

    Nonlinear Model Predictive Control (NMPC) is a control strategy based on repeatedly solving an optimal control problem. In this paper we present a new MPC framework for the JModelica.org platform, developed specifically for use in NMPC schemes. The new framework utilizes the fact that the optimal control problem to be solved does not change between solutions, thus decreasing the computation time needed to solve it. The new framework is compared to the old optimization framework in JModelica.o...

  6. Timing of subduction and exhumation in a subduction channel: Evidence from slab melts from La Corea Mélange (eastern Cuba)

    Blanco-Quintero, I. F.; Rojas-Agramonte, Y.; García-Casco, A.; Kröner, A.; Mertz, D. F.; Lázaro, C.; Blanco-Moreno, J.; Renne, P. R.

    High pressure igneous rocks (tonalites), generated by partial melting of subducted basaltic rocks accreted to the mantle wedge, are present in the La Corea serpentinite-matrix mélange (eastern Cuba) as centimeter- to meter-sized blocks and as concordant to crosscutting veins within high-pressure parent amphibolite blocks. The slab melts have adakitic signatures, in agreement with formation after partial melting of metabasite. Thermobarometric calculations indicate 620-680 °C and 13-15 kbar during crystallization of tonalites and down to 250-300 °C, 6 kbar during retrogression, indicating counter-clockwise P-T paths (hot subduction-cool exhumation). Free water required for melting of amphibolite at moderate temperature (700-750 °C) and moderate pressure (13-16 kbar) close to the wet basaltic solidus is inferred to have been provided after dehydration of sediments, altered basaltic crust and serpentinite of the subducting Proto-Caribbean lithosphere. Single zircon (SHRIMP) and phengite 40Ar/39Ar age data constrain the P-T-t evolution of the mélange from the timing of crystallization of melts at ~ 110-105 Ma to cooling at ~ 87-84 Ma, ca. 350 °C, ca. 9 kbar. These figures are consistent with subduction of an oblique ridge, shortly before 115 Ma. Furthermore, our data indicate very slow exhumation (ca. 1 mm/yr) in the subduction channel during the oceanic convergence stage (120-70 Ma) until final fast exhumation to the surface occurred at 70-65 Ma during a regional arc-platform collision event.

    2015-12-01

    This contribution provides an overview of the features of Paleomagnetism.org, a new open-source online environment for paleomagnetic analysis that is supported by all modern browsers on multiple platforms. The core functionality of Paleomagnetism.org is written in JavaScript and maintains an interactive website in which paleomagnetic data can be interpreted, evaluated, visualized, and exported. Although being an online platform, the data processing is performed client-sided within the browser to respect the integrity of the data and users. In the interpretation portal, principle component analysis (Kirschvink et al., 1981) can be applied on visualized demagnetization data (Zijderveld, 1967). The interpreted directions and great circles can be combined using the iterative procedure of (McFadden and McElhinny, 1988). The resulting magnetic directions can be used in the statistics portal or exported as raw tabulated data and figures. The available tools in the statistics portal cover standard Fisher statistics for directional data and virtual geomagnetic poles (Fisher, 1953; Butler, 1992; Deenen et al., 2011). Other tools include the eigenvector approach foldtest (Tauxe and Watson, 1994), a bootstrapped reversal test (Tauxe et al., 2009), and the classical reversal test of (McFadden and McElhinny, 1990). An implementation exists for the detection and correction of inclination shallowing in sediments (Tauxe and Kent, 2004; Tauxe et al., 2008) and a module to visualize custom or default APWP reference frames (Torsvik et al., 2012; Kent and Irving, 2010; Besse and Courtillot, 2002) for continent-bearing plates. Paleomagnetism.org provides an integrated approach for researchers to export tabulated and visualized (e.g. equal area projections) paleomagnetic data. The portals construct a custom exportable file that can be shared with other researchers and included in public databases. With a publication, this custom file can be appended and would contain all data used in the

    Full Text Available El desarrollo acelerado de las neurociencias en las últimas dos décadas permitió rescatar al cerebro de las sombras cartesianas donde se encontraba condenado, demostrándose que todo fenómeno psíquico, normal o morboso, tiene como sustento material a este órgano gestor de las funciones psíquicas. De esta manera quedó esclarecido que los trastornos mentales desencadenados por acontecimientos psicosociales estresantes actúan sobre el cerebro, provocando cambios neuroquímicos a nivel molecular responsables de la sintomatología que los tipifica, conjugándose etiopatogénicamente los factores biológicos, psicológicos y sociales gestores de estos desórdenes mentales. (1 Se distinguen en psiquiatría dos tipos de perfiles clínicos que los clásicos semiólogos clasificaron en síndromes orgánicos y funcionales; los primeros causados por alteraciones estructurales a nivel histopatológico en el cerebro o sus envolturas, nombradas afecciones orgánicas propiamente dichas, y síntomáticas cuando afectan el metabolismo cerebral a distancia; los segundos sustentan los cambios a nivel molecular, afectando la constitución química del cerebro por factores psicosociales, hereditarios y congénitos. (1 Los avances neurobiológicos esclarecen la multicausalidad de los trastornos mentales y el papel organogénico del cerebro, sustentado en su capacidad intrínseca de reflejar la realidad objetiva, que al perderse origina el espectro psicopatológico que hoy conocemos. (2 Algunos autores contemporáneos a partir del resurgimiento del protagonismo cerebral en la cristalización de los trastornos mentales, plantean que las fronteras entre lo orgánico y lo funcional se quebraron y que la enfermedad mental es orgánica en toda su extensión dada la obligada participación etiológica del cerebro.

  9. Leitura e diagnóstico do sintoma orgânico

    Directory of Open Access Journals (Sweden)

    Eisenbruch Renata Volich

    2000-01-01

    Full Text Available A psicanálise sublinha a subjetividade do corpo, dos afetos que o habitam, particularmente a angústia. Angústia enquanto afeto que participa das flutuações do nosso corpo. Afeto que mobiliza o corpo. O diagnóstico de certas patologias orgânicas não se faz pelo scanner mas pelo discurso. Referir-se à linguagem ao tratar da psicopatologia e do tratamento psicanalítico é essencial pois o sintoma não é indiferente ao discurso, o sintoma pode ser abordado pelo discurso. Se escolhermos falar do corpo que é atingido pela patologia orgânica nos reportamos ao fato que o corpo vivente não existe sem as incidências do inconsciente sobre ele. Isso nos conduz não somente às coordenadas do gozo do corpo mas também do desejo inconsciente enquanto vetor que parte do Outro materno e pode irromper no real do corpo da criança. A patologia da criança nos permite verificar o que está em questão no infantil. O sintoma é também o elemento que para cada ser, na sua singularidade, se subtrai da homeostase que o simbólico pode oferecer. O mistério da doença orgânica indica que o modelo resultante da estatística, como demonstram manuais de diagnóstico, é um certo resultado de cálculos do qual os indivíduos que encontramos numa clínica psicanalitica se afastam. É nisso que consiste sua subjetividade. A infelicidade estatística de cada patologia nunca fornece a soma das tragédias individuais.

  11. Extending ArXiv.org to Achieve Open Peer Review and Publishing

    CERN Document Server

    Boldt, Axel

    2010-01-01

    Today's peer review process for scientific articles is unnecessarily opaque and offers few incentives to referees. Likewise, the publishing process is unnecessarily inefficient and its results are only rarely made freely available to the public. Here we outline a comparatively simple extension of arXiv.org, an online preprint archive widely used in the mathematical and physical sciences, that addresses both of these problems. Under the proposal, editors invite referees to write public and signed reviews to be attached to the posted preprints, and then elevate selected articles to "published" status.

  6. Ultra-oxidized redox conditions in subduction mélanges? Decoupling between oxygen fugacity and oxygen availability in a metasomatic environment

    Science.gov (United States)

    Tumiati, Simone; Poli, Stefano; Godard, Gaston; Martin, Silvana; Malaspina, Nadia

    2014-05-01

    The manganese ore of Praborna (Italian Western Alps) is embedded within a metasedimentary sequence belonging to a subduction mélange equilibrated at high-pressure conditions (~2 GPa) during the Alpine orogenesis and record environmental conditions typical for a subducting slab setting. The pervasive veining of the ore and the growth of "pegmatoid" HP minerals suggest an open system with large fluid/rock ratio and a strong interaction with slab-derived fluids. This natural case provides an excellent natural laboratory for the study of the oxygen mobility in subducting oceanic slab mélanges at high-P, fluid-present conditions. The Mn-rich rocks in contact with the underlying sulphide- and magnetite-bearing metabasites, in textural and chemical equilibrium with the veins, contain braunite (Mn2+Mn3+6SiO12) + quartz + pyroxmangite (Mn2+SiO3), and minor hematite, omphacite, the epidote piemontite and spessartine-rich garnet. Similarly to Fe-bearing systems, Mn oxides and silicates can be regarded as natural redox-sensors, capable to monitor a process of fluid infiltration that could fix externally the intensive variable fO2 (or μO2). Sulphides are absent in these Mn-rich rocks, sulphates (barite, celestine) occurring instead together with As- and Sb oxides and silicates. On the basis of the observed assemblages, new thermodynamic calculations show that these mélange rocks are characterized by unrealistic ultra-oxidized states (ΔFMQ up to +12) if the chemical potential of oxygen (or the oxygen fugacity) is accounted for. However, if the molar quantity of oxygen in excess with reference to with reference to a system where all iron and manganese are considered to be ferrous, the ore appears only moderately oxidized, and comparable to typical subduction-slab mafic eclogites. Therefore, oxygen can be hardly considered a perfectly mobile component, even in the most favourable conditions. In the Earth's interior redox reactions take place mainly among solid oxides and

  7. Starstuff.org - Bridging the Cosmos Between Astronomers and the Public

    Science.gov (United States)

    Hamm, J. J.; Howell, D. A.

    1998-12-01

    Starstuff.org is a new web site featuring articles written by astronomers to promote general interest in astronomy and communicate directly the ideas and excitement that make astronomy popular with the public. Traditional media are limited as an outreach tool, because journalists and publishers decide which topics are newsworthy, and many facts are lost in the translation. Starstuff.org circumvents these problems by removing the middleman and allowing astronomers to communicate with the public directly. Readers can be assured of getting accurate information through the firsthand accounts of leaders in the field. This format also allows for the discussion of astronomical concepts and issues that may be important to astronomers but not considered newsworthy by journalists. The unique power of the computers and the internet as instructive tools is harnessed with features such as virtual reality (VRML) explorations of 3D concepts, interactive equations, animations to explain dynamic events, and hyperlinks to emphasize the connections between concepts and direct the reader to further resources. Topics may be explored in more creative ways and in greater depth than in traditional media, and astronomers can reach a wider audience than they could in a traditional lecture. The site's infrastructure, automated processing, and professional programmer/digital artist free contributors from having to know HTML, allowing them to concentrate on creative ways of presenting ideas. Any astronomer with email is encouraged to contribute.

  8. Hippocampome.org: a knowledge base of neuron types in the rodent hippocampus.

    2015-01-01

    Hippocampome.org is a comprehensive knowledge base of neuron types in the rodent hippocampal formation (dentate gyrus, CA3, CA2, CA1, subiculum, and entorhinal cortex). Although the hippocampal literature is remarkably information-rich, neuron properties are often reported with incompletely defined and notoriously inconsistent terminology, creating a formidable challenge for data integration. Our extensive literature mining and data reconciliation identified 122 neuron types based on neurotransmitter, axonal and dendritic patterns, synaptic specificity, electrophysiology, and molecular biomarkers. All ∼3700 annotated properties are individually supported by specific evidence (∼14,000 pieces) in peer-reviewed publications. Systematic analysis of this unprecedented amount of machine-readable information reveals novel correlations among neuron types and properties, the potential connectivity of the full hippocampal circuitry, and outstanding knowledge gaps. User-friendly browsing and online querying of Hippocampome.org may aid design and interpretation of both experiments and simulations. This powerful, simple, and extensible neuron classification endeavor is unique in its detail, utility, and completeness. PMID:26402459

  10. Geochemical and tectonic implications on plate-interface evolution achieved from high-pressure ultramafic rocks in mélange settings

    Science.gov (United States)

    Cannaò, E.; Agostini, S.; Scambelluri, M.; Tonarini, S.

    2014-12-01

    Geochemical studies of fluid-mobile elements (FME) joined with B, Sr and Pb isotopic analyses of high-pressure mélanges terranes help constraining tectonic processes and mass transfer during accretion of slab and suprasubduction mantle in plate-interface domains. Here we focus on ultramafic rocks from two plate interface settings: (I) metasediment-dominated mélange (Cima di Gagnone, CdG, Adula Unit), where eclogite-facies de-serpentinized garnet peridotite and chlorite harzburgite lenses are embedded in paraschist; (II) dominated by high-pressure serpentinite (Erro-Tobbio, ET, and Voltri Units, VU, Ligurian Alps). CdG metaperidotite shows low [B], negative δ 11B and high Sr and Pb isotopic ratios. As, Sb loss from metasediment and gain by garnet and chlorite metaperidotite points to exchange between the two systems. Presence of As and Sb in eclogite-facies peridotite minerals and preferential low-T mobility of such elements suggest that exchange was during early subduction burial and prior to eclogitization. Based on high [B], positive δ11B, oxygen and hydrogen isotope, the ET serpentinties were recently interpreted as supra-subduction mantle flushed by slab fluids (Scambelluri & Tonarini, 2012, Geology, 40, 907-910). Their 206Pb/204Pb and 87Sr/86Sr isotope ratios range between 18.300-18.514 and 0.7048-0.7060, respectively. Compared with ET rocks, VU serpentinites have higher As, Sb (up to 1.3 and 0.39 ppm, respectively) and are enriched in radiogenic Sr (up to 0.7105 87Sr/86Sr). This signature reflects interaction with fluids that exchanged with sedimentary rocks, either in outer rise environments or during accretion atop the slab. In the above cases, the serpentinized mantle rocks fingerprint interaction with fluids from different sources, indicating a timing of accretion to plate interface domains. We provide evidence that serpentinized mantle slices of different size and provenance (slab or wedge) accreted to plate interface domains since early subduction

    VHub (short for VolcanoHub, and accessible at vhub.org) is an online platform for barrier free access to high end modeling and simulation and collaboration in research and training related to volcanoes, the hazards they pose, and risk mitigation. The underlying concept is to provide a platform, building upon the successful HUBzero software infrastructure (hubzero.org), that enables workers to collaborate online and to easily share information, modeling and analysis tools, and educational materials with colleagues around the globe. Collaboration occurs around several different points: (1) modeling and simulation; (2) data sharing; (3) education and training; (4) volcano observatories; and (5) project-specific groups. VHub promotes modeling and simulation in two ways: (1) some models can be implemented on VHub for online execution. VHub can provide a central warehouse for such models that should result in broader dissemination. VHub also provides a platform that supports the more complex CFD models by enabling the sharing of code development and problem-solving knowledge, benchmarking datasets, and the development of validation exercises. VHub also provides a platform for sharing of data and datasets. The VHub development team is implementing the iRODS data sharing middleware (see irods.org). iRODS allows a researcher to access data that are located at participating data sources around the world (a cloud of data) as if the data were housed in a single virtual database. Projects associated with VHub are also going to introduce the use of data driven workflow tools to support the use of multistage analysis processes where computing and data are integrated for model validation, hazard analysis etc. Audio-video recordings of seminars, PowerPoint slide sets, and educational simulations are all items that can be placed onto VHub for use by the community or by selected collaborators. An important point is that the manager of a given educational resource (or any other

    Tonai, Satoshi; Ito, Shun; Hashimoto, Yoshitaka; Tamura, Hajimu; Tomioka, Naotaka

    2016-08-01

    We used the K-Ar ages of clay-sized mineral grains to investigate the timing of activity on the Minami-Awa Fault, which is a fossil seismogenic fault along a subducting plate interface separating the coherent strata of the Shimanto accretionary complex to the north from the tectonic mélange to the south. The K-Ar ages from the matrix shale of the mélange range from 85 to 48 Ma and decrease with decreasing amount of detrital mica, indicating that they record a mixture of authigenic illite related to burial diagenesis and detrital mica. In contrast, the K-Ar ages of an ultracataclasite within the fault core are significantly younger, ranging from 29 to 23 Ma, and are unrelated to grain size and amount of detrital mica. This indicates that s Ar diffused completely from the ultracataclasite between 29 and 23 Ma, which postdates the formation of authigenic illite by at least several million years. The diffusion of 40Ar in the ultracataclasite was probably caused by frictional heating or high-temperature fluid migration that occurred when the fault was reactivated. The results indicate that seismogenic faults that separate tectonic mélange from coherent strata in accretionary complexes may slip, not only during accretion, but also long after accretion.

  19. Barium-rich fluids and melts in a subduction environment (La Corea and Sierra del Convento mélanges, eastern Cuba)

    Science.gov (United States)

    Blanco-Quintero, Idael Francisco; Lázaro, C.; García-Casco, A.; Proenza, J. A.; Rojas-Agramonte, Y.

    2011-08-01

    Whole-rock compositions of muscovite-bearing amphibolite, trondhjemite, pegmatite and quartz-muscovite rocks from Sierra del Convento and La Corea mélanges (eastern Cuba), as well as mineralogy, record complex circulation of Ba-rich fluids and melts in the subduction environment. Partial melting of fluid-fluxed, MORB-derived amphibolite produced trondhjemite magmas that crystallized at depth, in some cases evolving into pegmatites. Qtz-Ms rocks probably crystallized from primary fluids derived from subducted sediments. All these rocks have elevated concentrations of large-ion lithophile elements, especially Ba (up to 11,810 ppm), presumably released from slab sediments by fluids and/or melts. Fluid-rock interaction produced crystallization of phengite in parental amphibolites. The phengite crystallized in all types of rocks is rich in Ba, with concentric zoning, characterized by Ba-rich cores and Ba-poor rims, indicating a compatible behaviour of Ba in the studied systems. Zoning in phengite is governed primarily by the celadonite (tschermak) exchange vector ((Mg,Fe)Si-(Al)-2), with more moderate contributions of the celsian (BaAl-(KSi)-1) and paragonite (NaK-1) exchange vectors. Late remobilization of Ba at relatively low temperature formed retrograde celsian. The compatible behaviour of Ba in the studied rocks strengthens the importance of the stability of phengite for the transfer of LIL elements from the subduction to the volcanic arc environments.

    Mutations in the potassium channel subunit KCNQ1 cause the human severe congenital deafness Jervell and Lange-Nielsen (JLN) syndrome. We applied a gene therapy approach in a mouse model of JLN syndrome (Kcnq1(-/-) mice) to prevent the development of deafness in the adult stage. A modified adeno-associated virus construct carrying a Kcnq1 expression cassette was injected postnatally (P0-P2) into the endolymph, which resulted in Kcnq1 expression in most cochlear marginal cells where native Kcnq1 is exclusively expressed. We also found that extensive ectopic virally mediated Kcnq1 transgene expression did not affect normal cochlear functions. Examination of cochlear morphology showed that the collapse of the Reissner's membrane and degeneration of hair cells (HCs) and cells in the spiral ganglia were corrected in Kcnq1(-/-) mice. Electrophysiological tests showed normal endocochlear potential in treated ears. In addition, auditory brainstem responses showed significant hearing preservation in the injected ears, ranging from 20 dB improvement to complete correction of the deafness phenotype. Our results demonstrate the first successful gene therapy treatment for gene defects specifically affecting the function of the stria vascularis, which is a major site affected by genetic mutations in inherited hearing loss.

    Full Text Available Ponderações sobre as emoções humanas apresentaram-se em toda a obra do bielorrusso L. S. Vigotski, desde sua juvenil crítica de arte. Nesse tópico, debateu a contribuição de vários autores: Freud, Claparède, Ribot, Lewin, Wundt. Entretanto, a perspectiva mais analisada por ele foi a teoria James-Lange. O objetivo deste artigo é discutir a extensa crítica que Vigotski dirigiu a ela no manuscrito “Utchenie ob Emotsiakh”, a qual se enquadrava numa ampla atitude teórico-metodológica do autor: a de compilar e relacionar o material fatual sem coordenação, expondo a luta de ideias filosóficas por detrás das psicológicas, de modo a abrir caminho para futuras investigações destinadas à superação do dualismo na psicologia. A partir dos principais fundamentos vigotskianos para futuros estudos, discutimos essa querela acerca das emoções, tema que o bielorrusso considerava a parte mais difícil e, possivelmente, a mais importante para o futuro da ciência psicológica.

    Full Text Available The aim of the performed investigations was the comparison of yield and dry matter content of carpophores from selected strains of Agaricus bisporus (Lange Imbach belonging to three types. Differences within the yielding of different strains of several types, as well as following flushes of yielding were found. In type U1 the highest yield was obtained by ‘Le Lion X1’ (175 g·kg-1 f.m. of substrate, in intermediate type - ‘Italspawn 56’ and ‘Sylvan 130’ (both 161 g·kg-1 f.m. of substrate and in type U3 - ‘Italspawn F62’ and ‘Polmycel 23’ (194 and 192 g·kg-1 f.m. of substrate. It was found that the dry matter content depended both on the strain and the flush. The highest dry matter content was determined within the third flush. The highest content of dry matter in carpophores was determined in the following strains of mushrooms: type U1 - ‘Italspawn F50’ (8.5%, intermediate type - ‘Hauser A1.5’ (9.2% and type U3 - ‘Italspawn F62’ (8.3%.

    Cornelia de Lange syndrome (CdLS) is a clinically and genetically heterogeneous congenital anomaly. Mutations in the NIPBL gene account for a half of the affected individuals. We describe a family with CdLS carrying a novel pathogenic variant of the SMC1A gene identified by exome sequencing. The proband was a 3-yr-old boy presenting with a developmental delay. He had distinctive facial features without major structural anomalies and tested negative for the NIPBL gene. His younger sister, mother, and maternal grandmother presented with mild mental retardation. By exome sequencing of the proband, a novel SMC1A variant, c.3178G>A, was identified, which was expected to cause an amino acid substitution (p.Glu1060Lys) in the highly conserved coiled-coil domain of the SMC1A protein. Sanger sequencing confirmed that the three female relatives with mental retardation also carry this variant. Our results reveal that SMC1A gene defects are associated with milder phenotypes of CdLS. Furthermore, we showed that exome sequencing could be a useful tool to identify pathogenic variants in patients with CdLS. PMID:26354354

    The Ormen Lange Onshore Processing Plant in Aukra municipality (Moere og Romsdal county) receives unprocessed gas and condensate from the Ormen Lange field in the Norwegian Sea. During processing of sales gas and condensate, the plant emits CO, Co2, Nox, CH4, NMVOC (including BTEX), SO2 and small amounts of heavy metals, as specified in the discharge permit issued by the Climate and Pollution Directorate. The plant started production in 2007, with A/S Norske Shell as operator. In general, emissions of nitrogen and sulphur-containing gasses may affect terrestrial ecosystems through acidification and fertilization of soil and vegetation. The emissions from the onshore plant are calculated to be below the current critical loads for the terrestrial nature types. However, the nitrogen background level in the area of influence is close to the critical loads for oligotrophic habitats. To be able to document any effects of emissions to air on terrestrial ecosystems, a monitoring program for vegetation and soil was established in 2008 in the area of influence from the Ormen Lange Onshore Plant. The monitoring is planned at regular intervals according to the same methods employed in 2008, with the first reanalysis in 2010. The benefits of the monitoring parameters will be continuously evaluated. Statnett has established a Reserve Power Plant with discharge permits of similar substances in the same area as the Ormen Lange Onshore Processing plant, and participates in an extended monitor program from 2010. In 2008 two monitoring sites were established, one with rather high deposition of nitrogen north of the plant within Gule-Stavmyran nature reserve in Fraena municipality (site Gulmyran) and one south of the plant on the island Gossa (site Aukra). Deposition values have been estimated by the Norwegian Institute for Air Research (NILU). Within each site integrated monitoring of the species composition of the vegetation, plant growth, and chemical content of plants and soil is

    White Dwarf Research Corporation is a 501(c)(3) non-profit organization dedicated to scientific research and public education on topics relevant to white dwarf stars. It was founded in 1999 in Austin, Texas to help fulfill the need for an alternative research center where scarce funding dollars could be used more efficiently, and to provide a direct link between astronomers who study white dwarf stars and the general public. Due to its administrative simplicity, WDRC can facilitate the funding of multi-institutional and international collaborations, provide seamless grant portability, minimize overhead rates, and actively seek non-governmental funding sources. I describe the motivation for, and current status of, one of the long-term goals of WDRC: to establish a permanent endowment for the operation of the Whole Earth Telescope.

    Women diagnosed with DCIS face complex treatment decisions and often do so with inaccurate and incomplete understanding of the risks and benefits involved. Our objective was to create a tool to guide these decisions for both providers and patients. We developed a web-based decision aid designed to provide clinicians with tailored information about a patient’s recurrence risks and survival outcomes following different treatment strategies for DCIS. A theoretical framework, microsimulation model (Soeteman et al., J Natl Cancer 105:774–781, 2013) and best practices for web-based decision tools guided the development of the decision aid. The development process used semi-structured interviews and usability testing with key stakeholders, including a diverse group of multidisciplinary clinicians and a patient advocate. We developed onlineDeCISion.​org to include the following features that were rated as important by the stakeholders: (1) descriptions of each of the standard treatment options available; (2) visual projections of the likelihood of time-specific (10-year and lifetime) breast-preservation, recurrence, and survival outcomes; and (3) side-by-side comparisons of down-stream effects of each treatment choice. All clinicians reviewing the decision aid in usability testing were interested in using it in their clinical practice. The decision aid is available in a web-based format and is planned to be publicly available. To improve treatment decision making in patients with DCIS, we have developed a web-based decision aid onlineDeCISion.​org that conforms to best practices and that clinicians are interested in using in their clinics with patients to better inform treatment decisions.

    The Kenting Mélange located in the Central Range-Hengchun Peninsula accretionary prism shows a chaotic block-in-matrix structure. It was considered to be mainly of sedimentary origin (olistostromes) in the early 1990s, but tectonic origin gradually becomes a mainstream point of view when a large number of marine data has been collected since 1990s. According to lots of field observation, we find these chaotic deposits consist of a variety of blocks, up to km in size, of different lithologies such as chrome-spinel, gabbros, basalt and sandstones. These blocks float in a muddy matrix commonly showing a pervasive scaly foliation. Moreover, sausage-shaped sandstone, mud veins intruded in the exotic blocks under high pressure and heterogeneous hydrofracture in the surface of sandstones can demonstrate the Kenting Mélange was a tectonic origin rather than olistostromes. The Kenting Mélange can be considered as a mega-sheared fault zone about 1 km wide and 20 km long that approximately parallel to the north part of Manila trench, it is the character of tectonic mélange as fault rock of subduction plate boundary. In comparing the Kenting Mélange with the famous tectonic mélange in the world such as the Mugi Mélange in the Shimento Belt, Japan and the Bobonaro Mélange in the western Banda orogen, Indonesia, it is interesting to note the similarities. Moreover, seismic reflection profiles and foraminifera analysis studied before can also support the tectonic origin. In summary, a hypothesis can be proposed that the Kenting Mélange is a tectonic mélange as fault rock of subduction plate boundary at the front of the Taiwan accretionary prism, it formed mostly at the base of the accretionary prism by stratal detachment and fluid-assisted remobilization above a basal decollement, and then exposed through the splay fault system along with the involvement of the exotic blocks and the original continuous sedimentary strata block. The Kenting Mélange represents fault rock

    Las nubes moleculares son regiones de formación de estrellas, con temperaturas cinéticas entre 10-50 K y densidades de 103-106 átomos cm-3. Su materia está formada por gas y polvo interestelar. Estas partículas de polvo están cubiertas por una fina capa de hielo, de unos 0.01 μm, que contiene H2O y a menudo CO, CO2, CH3OH y NH3. El hielo es presumiblemente irradiado por fotones ultravioleta y rayos cósmicos en las zonas poco profundas de las nubes moleculares y las regiones circunestelares. En un sistema de vacío, P ˜ 10-7 mbar, simulamos la deposición de hielo a partir de 10 K y la irradiación ultravioleta por medio de una lámpara de descarga de hidrógeno activada con microondas. La evolución del hielo se observa por medio de un espectrómetro infrarrojo. De este modo es posible determinar la composición del hielo observado en el medio interestelar y predecir la presencia de moléculas aún no detectadas en el espacio, que han sido producto del procesamiento del hielo en nuestros experimentos. También es posible calentar el sistema hasta temperatura ambiente para sublimar el hielo depositado. Cuando el hielo ha sido previamente irradiado, se observa un residuo compuesto por moléculas orgánicas complejas, algunas prebióticas, como varios ácidos carboxílicos, aminas, amidas, ésteres y en menor proporción moléculas heterocíclicas y aminoácidos. Algunas de estas moléculas podrían detectarse en estado gaseoso por medio de observaciones milimétricas y de radio. También podrían estar presentes en el polvo cometario, cuyo análisis químico está planeado por las misiones Stardust y Rosetta. Mientras tanto, nuestro grupo está llevando a cabo el análisis de partículas de polvo interplanetario (IDPs), algunas de las cuales pueden ser de origen cometario. Al igual que ocurre con los productos obtenidos por irradiación del hielo en nuestros experimentos, algunas IDPs son ricas en material orgánico que contiene oxígeno.

    Rubinstein-Taybi syndrome (RTS) and Cornelia de Lange syndrome (CdLS) are genetically heterogeneous multiple anomalies syndromes, each having a distinctive facial gestalt. Two genes (CREBBP and EP300) are known to cause RTS, and five (NIPBL, SMC1A, SMC3, RAD21, and HDAC8) have been associated with CdLS. A diagnosis of RTS or CdLS is molecularly confirmed in only 65% of clinically identified cases, suggesting that additional causative genes exist for both conditions. In addition, although EP300 and CREBBP encode homologous proteins and perform similar functions, only eight EP300 positive RTS patients have been reported, suggesting that patients with EP300 mutations might be escaping clinical recognition. We report on a child with multiple congenital abnormalities and intellectual disability whose facial features and complex phenotype resemble CdLS. However, no mutations in CdLS-related genes were identified. Rather, a novel EP300 mutation was found on whole exome sequencing. Possible links between EP300 and genes causing CdLS are evident in the literature. Both EP300 and HDAC8 are involved in the regulation of TP53 transcriptional activity. In addition, p300 and other chromatin associated proteins, including NIPBL, SMCA1, and SMC3, have been found at enhancer regions in different cell types. It is therefore possible that EP300 and CdLS-related genes are involved in additional shared pathways, producing overlapping phenotypes. As whole exome sequencing becomes more widely utilized, the diverse phenotypes associated with EP300 mutations should be better understood. In the meantime, testing for EP300 mutations in those with features of CdLS may be warranted. PMID:24352918

    Full Text Available Abstract Background Long QT syndrome (LQTS is a cardiac disorder characterized by prolonged QT intervals on electrocardiograms (ECG, ventricular arrhythmias, and sudden death. Clinically, two inherited forms of LQTS have been defined: autosomal dominant LQTS or Romano-Ward syndrome (RWS not associated with deafness and autosomal recessive LQTS or Jervell and Lange-Nielsen syndrome (JLNS associated with deafness. Methods A Chinese family with both RWS and JLNS was identified. Family members were diagnosed based on the presence of a prolonged QT interval as seen on a 12-lead ECG and a medical history of syncope, palpitation, and deafness. Mutational studies in the KCNQ1 potassium channel gene were performed using direct DNA sequence analysis and restriction length polymorphism analysis. Results The proband in the Chinese family and her brother had previously been diagnosed with JLNS, and two other members were affected with RWS. The proband was also affected with atrial fibrillation. A single nucleotide substitution of C to T at nucleotide 965 of KCNQ1 was identified, and the mutation resulted in the substitution of a threonine residue at codon 322 by a methionine residue (T322M. The novel heterozygous T322M mutation was identified in two patients with RWS, one member with borderline QTc, and two normal family members. The two JLNS patients in the family carried the homozygous T322M mutation. The T322M mutation was not found in 200 Chinese normal controls. Conclusion Our results suggest that T322M is a novel mutation that caused RWS with high intrafamilial variability in the heterozygous carriers and typical JLNS in the homozygous carriers within this Chinese family. The T322M mutation is the first mutation identified for JLNS in the Chinese population.

  14. Blueschist metamorphism and its tectonic implication of Late Paleozoic-Early Mesozoic metabasites in the mélange zones, central Inner Mongolia, China

    Blueschists in central Inner Mongolia are distributed as layers and blocks in mélanges including the southern zone in Ondor Sum area and the northern zone in Manghete and Naomuhunni areas. They have been attributed to the subduction of Early Paleozoic oceanic crust. Blueschists from Ondor Sum and Naomuhunni are characterized by occurrence of sodic amphibole coexisting with epidote, albite, chlorite, calcic amphibole (in Ondor Sum) and muscovite (in Naomuhunni). Blueschists in Manghete contain porphyroblastic albite with inclusions of garnet and epidote in a matrix dominated by calcic-sodic amphibole, epidote, chlorite, albite and muscovite. Phase equilibria modeling for three blueschist samples using pseudosection suggest that the AlM2 contents in sodic amphibole can be used as a good barometer in the limited assemblage involving sodic amphibole + actinolite + epidote + chlorite + albite + quartz under pressures 7-10 kbar. In the sodic amphibole-bearing assemblages, the NaM4 contents in sodic amphibole mainly decrease as temperature rises, being a potential thermometry. The calculated pseudosections constrain the P-T conditions of blueschists to be 3.2-4.2 kbar/355-415 °C in Ondor Sum, 8.2-9.0 kbar/455 °C-495 °C in Manghete and 6.6-8.1 kbar/420-470 °C in Naomuhunni. These P-T estimates indicate a rather high geothermal gradient of 18-25 °C/km for the blueschist metamorphism, being of intermediate P/T facies series. Available zircon U-Pb age data suggests that the protoliths of blueschists were formed later than Late Paleozoic-Early Mesozoic and metamorphosed soon afterwards. An alternative interpretation for the tectonic implication of blueschists in central Inner Mongolia is that they may be a new type attributed to closure of limited ocean basins and do not represent a tectonic regime occurred in conventional subduction setting.

    Full Text Available Abstract Background To assess patterns of injecting drug use and HIV prevalence among injecting drug users (IDUs in an international border area along a major heroin trans-shipment route. Methods Cross-sectional surveys of IDUs in 5 sites in Lang Son Province, Vietnam (n = 348 and 3 sites in Ning Ming County, Guangxi Province, China (n = 308. Respondents were recruited through peer referral ("snowball" methods in both countries, and also from officially recorded lists of IDUs in Vietnam. A risk behavior questionnaire was administered and HIV counseling and testing conducted. Results Participants in both countries were largely male, in their 20s, and unmarried. A majority of subjects in both countries were members of ethnic minority groups. There were strong geographic gradients for length of drug injecting and for HIV seroprevalence. Both mean years injecting and HIV seroprevalence declined from the Vietnamese site farthest from the border to the Chinese site farthest from the border. 10.6% of participants in China and 24.5% of participants in Vietnam reported crossing the international border in the 6 months prior to interview. Crossing the border by IDUs was associated with (1 distance from the border, (2 being a member of an ethnic minority group, and (3 being HIV seropositive among Chinese participants. Conclusion Reducing the international spread of HIV among IDUs will require programs at the global, regional, national, and "local cross border" levels. At the local cross border level, the programs should be coordinated on both sides of the border and on a sufficient scale that IDUs will be able to readily obtain clean injection equipment on the other side of the border as well as in their country of residence.

    In this study, the frequency of mass-wasting events and past storminess has been reconstructed throughout the Holocene (11,500 cal yr BP to present) from lacustrine sediments in lake Trehynnvatnet (33 m a.s.l.), which is located in a glacially carved valley at Nykvåg on the outmost coast of western Langøya, Vesterålen, northern Norway. Sediment cores (∼2-5 m long) have been examined by use of high-resolution magnetic susceptibility and XRF-scanning as well as grain size and loss-on-ignition analysis. In total 35 episodic event layers have been identified throughout the Holocene. The majority of these events are characterized as discrete coarse-grained sediment layers followed by normal grading, and are related to past mass-wasting activity within the catchment. Periods with high mass-wasting activity are dated to 11,000-10,500, 5500-4500, 4000-3500, 3000-2500, 2000-1000 and 500-0 cal yr BP. The continuous input of sand grains (>250 μm) has been systematically investigated throughout the sediment cores. The sand grains are related to catchment samples from the sandy beach deposits in Sandvikbukta c. 750 m away in SW direction, and are suggested to indicate (niveo-) aeolian influx to the lake. The content of sand grains varies greatly throughout the record, although there is a clear increase in influx of sand during the last 2800 years. Periods with high aeolian influx are proposed to indicate increased storminess, which occurred between 1600 and 1550 (350-400 CE), 1400-1300 (450-550 CE), 750-550 (1200-1400 CE) and 250-20 cal yr BP (1700-1930 CE), which to some degree coincides with periods of increased storminess and winter precipitation recorded in other studies around the North Eastern Atlantic region.

    Traditional continuing medical education (CME) depended primarily on periodic courses and conferences. The cost-effectiveness of these courses has not been established, and often the content is not tailored to best meet the needs of the students. Internet training has the potential to accomplish these goals. Over the last 10 years, we have developed a Web site entitled "Orthochina.org," based upon the wiki concept, which uses an interactive, case-based format. We describe the development of online case discussions, and various technical and administrative requirements. As of December 31, 2007, there were 33,984 registered users, 9,759 of which passed the confirmation procedures. In 2007, an average of 211 registrants visited daily. The average number of first page clicks was 4,248 per day, and the average number of posts was 70 per day. All cases submitted for discussion include the patient's complaint, physical examination findings, and relevant images based on specific criteria for case discussion. The case discussions develop well professionally. No spam posting or unauthorized personal advertisement is permitted. In conclusion, online academic discussions proceed well when the orthopaedic surgeons who participate have established their identities. PMID:18685911

    Planet Hunters (http://www.planethunters.org), part of the Zooniverse collection of citizen science projects, enlists the general public to visually identify transits in the publicly released Kepler data via the World Wide Web. The human eye and brain are well suited to picking out most transits that cannot be detected in periodograms and are missed by the automated search algorithms. With over 53,000 volunteers examining the light curves on the Planet Hunters interface, we have the ability to visually inspect the entire public dataset for signatures of exoplanet transits. Planet Hunters is thus a novel and complementary technique to the automated transit detection algorithms, providing an independent assessment of the completeness of the Kepler exoplanet inventory. For each of the 150,000 Kepler-monitored stars, approximately 10 users examine 30-day segments of the star's light curve, identifying potential transits. Planet Hunters classifications are processed through a pipeline which uses simulated transit light curves to assess the capabilities of individual volunteers. Weightings are assigned to individuals and an iterative process is used to converge on final classifications and identify planet candidates. We present the results from analyzing the first three quarters of Kepler observations ( 120 days of observations) and present planet candidates identified by Planet Hunters comparing to the Kepler team's published lists of planet candidates. In particular, we discuss the abundance of large planets (> 2 earth radii) on short period (< 15 days) orbits based on Planet Hunters detections.

    The National Wind Erosion Research Network was established in 2014 as a collaborative effort led by the USDA Agricultural Research Service and Natural Resources Conservation Service, and USDI Bureau of Land Management, to address the need for standardized measurements of wind erosion and its controlling factors. Data will be used to support model development and identification of improved land management strategies that have global applications. By applying standard methods, the Network will overcome the common challenge of synthesizing independent studies to assess local-to-national scale wind erosion and dust emission. Twelve intensively instrumented Network sites will be operational by spring 2016, providing high-resolution measurements of aeolian sediment transport rates, meteorological conditions and soil and vegetation properties. These initial sites are located across rangelands and croplands in New Mexico, Texas, Arizona, California, Nevada, Colorado, Utah, North Dakota, Idaho and Washington. A primary objective of the Network is to facilitate collaboration among Network sites and the wider research community to address basic research questions about aeolian processes, model development, and evaluate practical management options. In support of Network activities, winderosionnetwork.org was developed to serve as a Network data portal, and provide online information about the National Wind Erosion Research Network including protocols and results. The website provides a comprehensive resource for scientists and managers interested in engaging with the Network and accessing Network products. The Network provides exciting opportunities to engage in a national long-term wind erosion research program that promises significant impact for our understanding and ability to predict and evaluate aeolian processes across land cover types and land use systems.

    Full Text Available Agricultural production systems have to combine management practices in order to sustain soil's profitability and quality. Organic farming is gaining worldwide acceptance and has been expanding at an annual rate of 20% in the last decade, accounting for over 24 million hectares worldwide. Organic practices avoid applications of synthetic fertilizers and pesticides, rely on organic inputs and recycling for nutrient supply, and emphasize cropping system design and biological processes for pest management, as defined by organic farming regulation in the world. In comparison with conventional farming, organic farming has potential benefits in improving food quality and safety. Plant production in organic farming mainly depends on nutrient release as a function of mineralization processes in soils. The build-up of a large and active soil microbial biomass is important pool of accessible nutrients, therefore, is an important priority in organic farming. In organic farming, there is positive effect of quantity and quality of inputs of organic residues on soil microbial biomass. In this way, the organic systems are extremely important for the increase of the soil fertility and the maintenance of the environmental sustainability.A produção agrícola tem de combinar práticas para prover a sustentabilidade do solo.

    Full Text Available This paper assesses different butanol–gasoline blends used in a port fuel-injection, spark-ignition engine to quantify the influence of butanol addition on the emission of unburned hydrocarbons, carbon monoxide, and nitrogen oxide. Furthermore, in-cylinder pressure was measured to quantify combustion stability and to compare the ignition delay and fully developed turbulent combustion phases as given by 0%–10% and 10%–90% Mass Fraction Burned (MFB. The main findings are: 1 a 40% butanol/60% gasoline blend by volume (B40 minimizes HC emissions; 2 no significant change in NOx emissions were observed, with the exception of the 80% butanol/20% gasoline blend; 3 the addition of butanol improves combustion stability as measured by the COV of IMEP; 4 butanol added to gasoline reduces ignition delay (0%–10% MFB; and 5 the specific fuel consumption of B40 blend is within 10% of that of pure gasoline for stoichiometric mixture.

    The present study was designed to find out whether the synthetic pentasaccharide SR 90107A/Org 31540, which is presently being evaluated in clinical trials as an antithrombotic agent, influences lipoprotein metabolism in rats as determined by plasma triglyceride (TG) lipase activity. A comparison with three clinically used sulphated polysaccharides-unfractionated heparin (UFH), low molecular weight heparin (LMWH) and pentosan polysulphate (PPS)- was performed. UFH evoked a dose-dependent increase in plasma TG lipase activity which plateaued at doses > or = 1 mg/kg i.v.. PPS and LMWH demonstrated a lower efficacy than heparin at 0.3 and 1 mg/kg i.v., but the maximum lipase releasing effect at 3 mg/kg i.v. was identical for UFH, PPS and LMWH. SR 90107A/Org 31540 did not release TG lipase activity at single i.v. doses up to 3 mg/kg. Repeated-dose experiments with SR 90107A/Org 31540 (1 mg/kg s.c. for 9 days) revealed no influence on the lipase releasing effect of UFH (1 mg/kg i.v. on day 10). These results demonstrate that SR 90107A/Org 31540 does not influence lipid metabolism in rats through lipase release, suggesting that SR 90107A/Org 31540 may offer an advantage over UFH and LMWH in clinical situations where an anticoagulant/antithrombotic effect is desired, but both an increase in plasma free fatty acids and atherogenic alterations of lipoprotein metabolism are considered harmful.

    2013-01-01

    For the reconstruction of Alpine tectonics of the Eastern Alps, the evaporitic Permian to Lower Triassic Haselgebirge Formation plays a key role in (1) the origin of Haselgebirge bearing nappes, (2) the inclusion of magmatic and metamorphic rocks revealing tectonic processes not preserved in other units, and (3) the debated mode of emplacement of the nappes, namely gravity-driven or tectonic. Within the Moosegg quarry of the central Northern Calcareous Alps gypsum/anhydrite bodies are tectonically mixed with lenses of sedimentary rocks and decimeter- to meter-sized tectonic clasts of plutonic and subvolcanic rocks and rare metamorphics. We examined various types of (1) widespread biotite–diorite, meta-syenite, (2) meta-dolerite and rare ultramafic rocks (serpentinite, pyroxenite) as well as (3) rare metamorphic banded meta-psammitic schists and meta-doleritic blueschists. The apparent 40Ar/39Ar biotite ages from three biotite–diorite, meta-dolerite and meta-doleritic blueschist samples with variable composition and fabrics range from 248 to 270 Ma (e.g., 251.2 ± 1.1 Ma) indicating a Permian age of cooling after magma crystallisation or metamorphism. The chemical composition of biotite–diorite and meta-syenite indicates an alkaline trend interpreted to represent a rift-related magmatic suite. These, as well as Permian to Jurassic sedimentary rocks, were incorporated during Cretaceous nappe emplacement forming the sulphatic Haselgebirge mélange. The scattered 40Ar/39Ar white mica ages of a meta-doleritic blueschist (of N-MORB origin) and banded meta-psammitic schist are ca. 349 and 378 Ma, respectively, proving the Variscan age of pressure-dominated metamorphism. These ages are similar to detrital white mica ages reported from the underlying Rossfeld Formations, indicating a close source–sink relationship. According to our new data, the Haselgebirge bearing nappe was transported over the Lower Cretaceous Rossfeld Formations, which include many clasts

    2009-04-01

    The provenance of monuments often is a striking question which science has to deal with. Especially petrographic and geochemical data of quarries are not or just partially published by various working groups. Often these data are hidden in "grey literature" and not available to the scientific community. These data, that also include photographs and maps shall be made accessible to the entire scientific community by the interdisciplinary information system www.saxa-loquuntur.org. The information system consists of two main databases: a) The quarry database, containing the following parameter: general quarry information, localization, material, geological information, dating of quarrying phases, quarry morphology, signs of treatment, historic infrastructure, semi finished goods, archaeological findings, authors and literature; b) The sample database for quarries and monuments, containing the following parameter: sample information, material, macroscopical -, microscopical -, geochemical -, X-RAY data, material technical properties, authors and literature. Because of the flexible structure of the analytical section new methods can be included easily. For the communication between the scientific fields of archaeology on one hand and natural sciences on the other a simplified interactive rock thesaurus was developed based on the IUGS rock nomenclature. An interlink between the sample database to various monument databases like VBI ERAT LUPA, Hispania Epigraphica etc. is established. This link provides additional information, like archaeological and epigraphical monument description and enables a full interdisciplinary monument analysis. The databases can be queried by simple and advanced search methods. The information system will provide visualisation tools for geochemical data, a photo board for the comparison of thin sections, and a cartographical visualisation of the search results for the area of the whole Roman Empire. Currently, the quarry and sample database

    Tiwari, Sandip

    2004-03-01

    A major challenge in science and engineering research at the nano-scale, and particularly for condensed matter, is the availability of infrastructure that can allow easy and quick implementation of structures, devices, or more complex systems necessary for making rigorous measurements or for other exploratory directions of interest. The experiments connect across length scales - nanometer and up, employ a variety of materials and techniques of assembly and patterning, and require a complex knowledge-mix derived from other research areas and tools that require skill and are hard to access. The National Nanotechnology Infrastructure Network (NNIN; www.nnin.org) is an NSF-funded infrastructure of open shared facilities across the country that enables the national community to pursue research and technology development that can benefit from nanotechnology. The NNIN provides easy hands-on access to external users, remote usage, staff support, low cost usage, knowledge infrastructure, and brings together an extensive coordinated array of instruments for fabrication, synthesis, and characterization together with other infrastructure.

    Gebhardt, Karl; Benningfield, D.; Preston, S.

    2013-01-01

    The StarDate Black Hole Encyclopedia website was developed over the past seven years to provide an extensive but easy-to-read resource for the public and students. A Spanish-language version, Enciclopedia de agujeros negros, is also available at blackholes.radiouniverso.org. Evaluation shows that the sites are used by the public, students, and astronomy professionals, and the site is among the top references in most web searches for individual black holes. The site comprises seven major subsections: Basics, Directory, Research, History, Pop Culture, News, and Resources. The Basics section introduces black holes, explains how they are discovered and studied, and covers their basis in the theory of gravity. This section also includes a six-minute video introduction, “Black Holes: Stranger than Fiction.” The Directory section contains extensive descriptions of more than 80 well-known stellar, intermediate, and supermassive black holes as well as images and vital statistics of each. The Research section takes a look at three NSF-funded projects, including the work of Andrea Ghez, Karl Gebhardt and Jenny Greene, and the LIGO project. The History section provides a timeline of black holes from Isaac Newton to the present. Some of the best and worst roles played by black holes in films, TV shows, and books are included in the Pop Culture section (and pop culture references and images are sprinkled through the rest of the site). An archive of news reports about black holes is available in the News section, which provides links to the original stories or press releases. And the Resources section offers FAQs, articles from StarDate magazine and radio programs, activities for students that are tied to national standards, a glossary, and a reading list of books and websites. We have conducted both quantitative and qualitative evaluation on the black hole websites. This material is based upon work supported by the National Science Foundation under Grant No. 0935841. Any

  12. Des forêts mélangées, une stratégie pour produire du bois face aux enjeux énergétiques et climatiques ? Mixing tree species: a strategy to face energy and climate issues?

    PEROT, Thomas ; VALLET, Patrick

    2012-01-01

    Full Text Available Garantir une offre en bois suffisante sans nuire à l'équilibre des écosystèmes dans un contexte de changement climatique est un des principaux objectifs visés par les recherches en gestion forestière. Le mélange d'espèces d'arbre au sein d'un peuplement forestier est une stratégie qui peut répondre à ces nouveaux enjeux. À Irstea, des travaux sont déjà engagés pour améliorer les connaissances sur le fonctionnement des écosystèmes forestiers mélangés et proposer des modes de gestion adaptés aux différents types d’assemblage d’espèces.Mixing tree species is a strategy that may have several advantages in terms of wood productivity. This strategy may have a positive effect on productivity and could limit the consequences of the weakening or disappearance of a species because of climate change. Nevertheless, the link between productivity and mixture is a hard topic and depends on a combination of factors that vary in space and time. Using data from the National Forest Inventory and long-term experiments are two complementary approaches to improve our knowledge on the functioning of mixed forests and to be able to define management strategies adapted to the different kinds of species assemblages and for different climatic conditions.

  18. Usage of the www.2aida.org AIDA diabetes software Website: a pilot study.

    Science.gov (United States)

    Lehmann, Eldon D

    2003-01-01

    AIDA is a diabetes-computing program freely available from www.2aida.org on the Web. The software is intended to serve as an educational support tool, and can be used by anyone who has an interest in diabetes, whether they be patients, relatives, health-care professionals, or students. In previous "Diabetes Information Technology & WebWatch" columns various indicators of usage of the AIDA program have been reviewed, and various comments from users of the software have been documented. One aspect of AIDA, though, that has been of considerable interest has been to investigate its Web-based distribution as a wider paradigm for more general medically related usage of the Internet. In this respect we have been keen to understand in general terms: (1) why people are turning to the Web for health-care/diabetes information; (2) more specifically, what sort of people are making use of the AIDA software; and (3) what benefits they feel might accrue from using the program. To answer these types of questions we have been conducting a series of audits/surveys via the AIDA Website, and via the software program itself, to learn as much as possible about who the AIDA end users really are. The rationale for this work is that, in this way, it should be possible to improve the program as well as tailor future versions of the software to the interests and needs of its users. However, a recurring observation is that data collection is easiest if it is as unobtrusive and innocuous as possible. One aspect of learning as much as possible about diabetes Website visitors and users may be to apply techniques that do not necessitate any visitor or user interaction. There are various programs that can monitor what pages visitors are viewing at a site. As these programs do not require visitors to do anything special, over time some interesting insights into Website usage may be obtained. For the current study we have reviewed anonymous logstats data, which are automatically collected at many

  19. Analysis of AntarcticGlaciers.org: a website used to communicate glaciology by an academic (Invited)

    Science.gov (United States)

    Davies, B. J.

    2013-12-01

    Research into polar science is driven by humanity's pressing concerns about environmental issues and climate change. The effective communication of this science is vital for it to realise its societal and political relevance. However, effective science communication has proved challenging for many reasons, including biased media presentation, lack of time and funds, lack of training, fear of attack by denialists, and poor career credit given for outreach and education work. A key question is how time-poor researchers, whilst working in full-time academic positions, can implement effective outreach strategies with little budget and few resources, that satisfies not only their personal desire to publicise and communicate their work, but also the demands of their research funder. Science websites and blogs offer one possibility, but there is little critical evaluation as to their effectiveness. The aim of this work is to evaluate a website and social medial tools written by an academic that was established to communicate peer-reviewed science. The goal of www.AntarcticGlaciers.org is to communicate key scientific concepts and to deliver new research findings via a professional, attractive, website and blog, supported by a strong social media presence. The objectives were to 1) to clearly explain and illustrate key concepts in glaciology as well as the latest developments in Antarctic research; 2) to be well aligned with national school curriculums, and to support school and university learning; 3) to include interactive features and social networking tools to encourage engagement and discourse; 4) to be aware of and well aligned with the website's intended audience. One year after website launch, the website was evaluated using a combination of an online feedback form, Google Analytics and analysis of Twitter followers. Our analysis shows that just one year after launch the website is a useful information resource, with some aspects that do challenge the knowledge

  1. OrgConv: detection of gene conversion using consensus sequences and its application in plant mitochondrial and chloroplast homologs

    Directory of Open Access Journals (Sweden)

    Hao Weilong

    2010-03-01

    Full Text Available Abstract Background The ancestry of mitochondria and chloroplasts traces back to separate endosymbioses of once free-living bacteria. The highly reduced genomes of these two organelles therefore contain very distant homologs that only recently have been shown to recombine inside the mitochondrial genome. Detection of gene conversion between mitochondrial and chloroplast homologs was previously impossible due to the lack of suitable computer programs. Recently, I developed a novel method and have, for the first time, discovered recurrent gene conversion between chloroplast mitochondrial genes. The method will further our understanding of plant organellar genome evolution and help identify and remove gene regions with incongruent phylogenetic signals for several genes widely used in plant systematics. Here, I implement such a method that is available in a user friendly web interface. Results OrgConv (Organellar Conversion is a computer package developed for detection of gene conversion between mitochondrial and chloroplast homologous genes. OrgConv is available in two forms; source code can be installed and run on a Linux platform and a web interface is available on multiple operating systems. The input files of the feature program are two multiple sequence alignments from different organellar compartments in FASTA format. The program compares every examined sequence against the consensus sequence of each sequence alignment rather than exhaustively examining every possible combination. Making use of consensus sequences significantly reduces the number of comparisons and therefore reduces overall computational time, which allows for analysis of very large datasets. Most importantly, with the significantly reduced number of comparisons, the statistical power remains high in the face of correction for multiple tests. Conclusions Both the source code and the web interface of OrgConv are available for free from the OrgConv website http

    Full Text Available Na determinação dos teores de carbono (C em resíduos orgânicos, são utilizadas variações de marchas analíticas empregadas para solos, sem a necessária calibração. Assim, torna-se necessário avaliar e calibrar métodos de determinação dos teores de C e de matéria orgânica (MO nesses materiais, tendo como referência o método da combustão seca. Objetivou-se neste estudo: avaliar métodos de determinação dos teores de carbono total (CT, carbono orgânico (CO e MO em amostras de resíduos orgânicos diversificadas; determinar um modelo matemático de conversão de C e MO de um método analítico para outro; e avaliar a possibilidade de o método da mufla ser utilizado em rotina de laboratórios para análise de teores de MO e inferência de teores de CT em resíduos orgânicos. Foram avaliados os teores de CT, CO e MO em 42 amostras de compostos, estercos, resíduos vegetais, lodos de esgoto e camas de frango e de suíno, cujas coletas foram realizadas em 2010, em municípios do Sul de Minas Gerais e em Jundiaí-SP. As amostras foram secas em estufa a 65 ºC, por 48 h, maceradas e passadas em peneiras com malha de 0,250 mm e analisadas. Os métodos utilizados nas análises foram: Walkley-Black modificado - Yeomans & Bremner (YB, combustão seca a 950 ºC (analisador TOC e combustão em mufla a 550 ºC, para as determinações de CO, CT e MO, respectivamente. Os teores de CT nos resíduos orgânicos variaram de 8,5 a 51,4 %. O método de Yeomans & Bremner subestima os teores de C em relação ao método da combustão seca. Em função da determinação dos teores de MO e CO e de uso de equações matemáticas, é possível estimar os teores de CT pelo método da combustão seca.

    Full Text Available Introducción: El nitrógeno es el nutriente más demandado por los árboles de nogal pecanero, por lo que es considerado un factor limitante para su desarrollo, producción y calidad de la nuez. Sin embargo, ante el aumento en el precio de los fertilizantes y sus efectos adversos en el ambiente, actualmente es más evidente la necesidad de aplicar nutrientes de manera sustentable. Una alternativa para disminuir la aplicación de fertilizantes nitrogenados inorgánicos en nogal pecanero, es complementarlo con composta, humus de lombriz, lixiviado de lombriz y microorganismos potenciadores de la fertilidad del suelo, como son las micorrizas, entre otros. Por lo que el objetivo del estudio fue reducir la aplicación de nitrógeno inorgánico al suelo mediante la adición de enmiendas orgánicas y microorganismos potenciadores de la fertilidad del suelo sin afectar producción ni calidad. Método: El estudio se realizó en el municipio de Aldama, Chihuahua, durante los ciclos 2010-2012 en árboles ‘Western Schley’, se utilizó una estructura Taguchi L16 para cuatro factores y cuatro niveles para cada factor: nitrógeno 330, 220, 110 y 0 kg ha-1; composta 0, 2.5, 5.0, 7.5 t ha-1; humus de lombriz (OptiHumusMR 0, 1.5, 3.0, 4.5 t ha-1 y micorrizas (Sehumic-VamMR 0, 7.5, 15.0, 22.5 g pulg-1 de tronco. Se determinó el contenido de materia orgánica y nitratos en el suelo, producción y calidad de la nuez, los cuales se analizaron por superficie de respuesta. Resultados: A pesar de que para producir 2.9 t ha-1 se logró reducir la aplicación de nitrógeno, este nivel no permitió obtener una buena calidad de la nuez ni alcanzar un contenido adecuado de materia orgánica y nitratos en suelo. Para un rendimiento de 2.9 t ha-1 con 153 nueces kg-1 y 59.4% de nuez comestible, 1.06% de materia orgánica y 183 ppm de nitratos en suelo se requirieron 305 kg de N, 6600 kg de composta, 3500 kg de humus de lombriz y 18 g de micorrizas por pulg-1 de tronco

  8. B, Sr and Pb isotope geochemistry of high-pressure Alpine metaperidotites monitors fluid-mediated element recycling during serpentinite dehydration in subduction mélange (Cima di Gagnone, Swiss Central Alps)

    Tectonic mixing of slab- and mantle-derived materials at the interface between converging plates highly enhances fluid-mediated mass transfer from the slab to the overlying mantle. Subduction mélanges can provide information about the interaction among different slices accreted at plate interface domains, with implications on the tectonic and geochemical evolution of the plate-interface itself. At Cima di Gagnone, pelitic schists and gneiss enclose chlorite harzburgite and garnet peridotite lenses, like in subduction mélanges located in-between downgoing slabs and overlying mantle. These peridotites host MORB-type eclogite and metarodingite, and derive from dehydration of serpentinized mantle protoliths. Their enrichment in fluid-mobile B, As, Sb, U, Th is the result of an early-stage oceanic serpentinization, followed by interaction with host metasediments during subduction burial. Here we define the element exchange process in the Gagnone mélange by means of the B, Sr and Pb isotope analysis of its main lithologies (ultramafic, mafic rocks and paragneiss). The 87Sr/86Sr and 206Pb/204Pb ratios of ultramafic rocks (0.7090-0.7124 and 18.292-18.837, respectively) show enrichments in radiogenic Sr and Pb after exchange with the host paraschist (up to 0.7287 87Sr/86Sr; 18.751 206Pb/204Pb). The δ11B values of peridotites (down to -10‰) point to a combined effect of (1) 11B release to deserpentinization fluids (serpentinized protoliths likely had positive δ11B and lower radiogenic Sr, Pb), and of (2) exchange with fluids from the surrounding metasediments. The whole Gagnone rock-suite is finally overprinted by retrograde fluids that essentially bring to an increase in radiogenic Pb (about 19.0 206Pb/204Pb) and to values of 0.710 87Sr/86Sr and of -10‰ δ11B. The recognition of different stages of interaction between mantle rocks and sedimentary/crustal reservoirs allows us to define the geochemical effects related to the early coupling of such rocks along the

    Based on the historical data that are extracted from a time series of satellite images, SLEUTH has been employed to simulate the urban growth and land use evolution in Jing-Jin-Lang area. To make SLEUTH applicable to Jing-Jin-Lang area,a number of calibrations should be done for the model. After calibrations,SLEUTH is used for "backcasting" of urban extent and land use/cover change with spatiotemporal interpolation during 1 985 to 2008.The simulated results are analyzed with historical data. On this basis, SLEUTH used as a forecasting tool to simulate the process of LUCC during 2009 to 2020 respectively. Using SLEUTH model, urban growth tendency in future was forecasted. The results indicated that, margin growth occupied dominant station relative to other growth method. In future, it was going to grow outward continually taking old urban area as the center all the same. At the same time, it was traffic system nowadays that was going to have an important influence to urban development in Jing-Jin-Lang area. At last, through using qualitative and quantitative method,urban expansion driving factors were discussed. Natural environment, national macroscopic policy regulation,traffic, development zone construction and special factors were important to urban growth in Jing-Jin-Lang area.The principal component analysis showed that, population-culture-economy factor and economy factor and economy-environment factor was respectively the first principal component to influence urban growth in Beijing and Tianjin and Langfang.%利用遥感和CIS技术获取历史数据,采用SLEUTH模型,对京津廊坊地区城市增长和土地利用演化进行模拟.模拟过程中,通过获取模型对于城市土地利用演化模拟的最佳模型参数系列.实现SLEUTH模型的本地化,重建了研究区1985-2008年城市土地利用历史动态演化过程,并模拟其未来动态扩展趋势,为研究区城市发展和城市规划提供科学依据.最后.通过对社会经济驱

  11. Environmental monitoring program for the Ormen Lange Onshore Processing Plant and the Reserve Power Plant at Nyhamna, Gossa. Monitoring of vegetation and soil: re-analyses and establishment of new monitoring plots in 2010

    International Nuclear Information System (INIS)

    The Ormen Lange Onshore Processing Plant in Aukra municipality (Moere og Romsdal county) receives unprocessed gas and condensate from the Ormen Lange field in the Norwegian Sea. During processing of sales gas and condensate, the plant emits CO, Co2, Nox, CH4, NMVOC (including BTEX), SO2 and small amounts of heavy metals, as specified in the discharge permit issued by the Climate and Pollution Directorate. The plant started production in 2007, with A/S Norske Shell as operator. In general, emissions of nitrogen and sulphur-containing gasses may affect terrestrial ecosystems through acidification and fertilization of soil and vegetation. The emissions from the onshore plant are calculated to be below the current critical loads for the terrestrial nature types. However, the nitrogen background level in the area of influence is close to the critical loads for oligotrophic habitats. To be able to document any effects of emissions to air on terrestrial ecosystems, a monitoring program for vegetation and soil was established in 2008 in the area of influence from the Ormen Lange Onshore Plant. The monitoring is planned at regular intervals according to the same methods employed in 2008, with the first reanalysis in 2010. The benefits of the monitoring parameters will be continuously evaluated. Statnett has established a Reserve Power Plant with discharge permits of similar substances in the same area as the Ormen Lange Onshore Processing plant, and participates in an extended monitor program from 2010. In 2008 two monitoring sites were established, one with rather high deposition of nitrogen north of the plant within Gule-Stavmyran nature reserve in Fraena municipality (site Gulmyran) and one south of the plant on the island Gossa (site Aukra). Deposition values have been estimated by the Norwegian Institute for Air Research (NILU). Within each site integrated monitoring of the species composition of the vegetation, plant growth, and chemical content of plants and soil is

    Full Text Available Le but de cet article est de discuter quelques expériences de base concernant le mélange dans les écoulements turbulents qui sont susceptibles de fournir des éléments de compréhension concernant les principaux mécanismes gouvernant les processus de mélange turbulent. La littérature ne fournit en fait qu'un petit nombre de telles situations physiques fondamentales, en partant des plus simples qui concernent le mélange dans des situations statistiquement homogènes et isotropes, pour aller vers des situations complexes comme les couches de mélange qui, au contraire, sont inhomogènes et anisotropes. Ces résultats expérimentaux permettent de dresser un certain nombre de conclusions concernant des mécanismes moyens clés, comme le transfert des grandes vers les petites échelles du champ de concentration, et sur quelques lois d'échelles que l'on peut déduire de leur compréhension. Néanmoins, le problème de la topologie des plus fines échelles du champ de concentration reste ouvert, et particulièrement dans les liquides où le nombre de Schmidt est élevé et, en conséquence, où ces échelles sont d'autant plus faibles. Seuls quelques travaux récents utilisant les techniques d'analyse d'images donnent des réponses à cette question importante pour la modélisation du processus de diffusion moléculaire. Les différents résultats des théories de la turbulence nécessaires à la discussion sont rappelés sans démonstration mais en insistant sur le sens physique des relations qui les traduisent. The aim of this paper is to discuss some basic experiments on mixing by turbulent flows, which give a clear understanding of the main mechanisms entering into the mixing process. A very small number of such fundamental physical situations may be found in the literature, from the simplest one concerning mixing in homogeneous turbulence up to more complex situations such as those encountered in mixing layers, which are strongly

    Full Text Available The Tephra2 numerical model for tephra fallout from explosive volcanic eruptions is specifically designed to enable students to probe ideas in model literacy, including code validation and verification, the role of simplifying assumptions, and the concepts of uncertainty and forecasting. This numerical model is implemented on the VHub.org website, a venture in cyberinfrastructure that brings together volcanological models and educational materials. The VHub.org resource provides students with the ability to explore and execute sophisticated numerical models like Tephra2. We present a strategy for using this model to introduce university students to key concepts in the use and evaluation of Tephra2 for probabilistic forecasting of volcanic hazards. Through this critical examination students are encouraged to develop a deeper understanding of the applicability and limitations of hazard models. Although the model and applications are intended for use in both introductory and advanced geoscience courses, they could easily be adapted to work in other disciplines, such as astronomy, physics, computational methods, data analysis, or computer science.

    Full Text Available El suelo es un recurso natural no renovable, se considrea como un cuerpo tridimensional  que presenta propiedades físicas, químicas y biológicas; en él habitan macro, mezo y microorganismos; además, las plantas se sostienen y toman los minerales de él. El componente sólido del suelo, contiene una fracción de materia orgánica, que le confiere unas condiciones apropiadas para el desarrollo de las plantas y demás habitantes del suelo; esta proviene de residuos vegetales y animales vivos o muertos que provocan en el  suelo diferentes características, como capacidad de intercambio catiónbico CIC, conductividad eléctrica CE, pH, color, temperatura, densidad, permeabilidad, textura, estructura, entre otras. Las diferentes actividades agrícolas o pecuarias deterioran estas condiciones  y en consecuencia disminuyen la capacidad productiva. Por esta razón, la adición de materia organiza, a través de los abonos orgánicos fermentados AOF, se convierte en una alternativa para mejorar a nutrición de las plantas, la alimentación de los organismos y las propiedades del suelo.

  20. Holocene evolution of Itapeva Lake, Rio Grande do Sul, Brazil: Palynomorphs C org, N, and S records

    Meyer, Karin Elise Bohns; Reichhart, Karin; Ashraf, Abdul Rahman; Marques-Toigo, Marleni; Mosbrugger, Volker

    2005-06-01

    Holocene coastal environmental changes are interpreted from a 590 cm long core taken from Itapeva Lake in the northern coastal plain, Rio Grande do Sul, Brazil. The sediment core is radiocarbon dated at 211 cm depth (6460±40 yr B.P.) and studied by geochemistry and palynomorph analyses. The Pleistocene-Holocene boundary is predicted at the top of a glauconitic sand layer at 330 cm depth. On the basis of C org, N, S, and palynomorph data, it is possible to distinguish four zones related to the Holocene transgression-regression cycle, as well as proxies for the salinity trends and organic matter source. The start of Zone 1 represents the oldest Holocene sedimentary record in the core. Palynomorphs reveal a marsh environment with a freshwater influence. In Zone 2, Operculoclinium centrocarpum and high S values indicate brackish water and reflect a Holocene sea-level rise related to the postglacial marine transgression. The high amount of Cyperaceae pollen grains and a significant C org increase in Zone 3 indicate a typical marsh environment with episodes of marine water that reflect a regression phase. Salvinia natans (L) All. and Cyperaceae pollen grains are the most significant palynomorphs in Zone 4, which characterizes a freshwater marsh.

Duas populações de cenoura em fase de melhoramento e quatro cultivares comerciais foram plantados em novembro de 2007 no campo nos dois sistemas de produção, com delineamento de blocos casualizados com quatro repetições e parcelas de 1 m², com 100 plantas por parcela. Aos 90 dias após o semeio, 20 raízes por parcela foram colhidas e avaliadas para caracteres fenotípicos. Foi realizada análise de variância com determinação da interação entre tratamentos e sistemas de produção, correlações fenotípicas, análise de trilha e os ganhos com as seleções direta e correlacionada. Observouse que a quase totalidade das correlações medianas acima de 0,30, bem como os maiores efeitos diretos da análise de trilha e os maiores ganhos diretos e indiretos estimados, foi repetida nos dois sistemas, indicando que eles foram muito semelhantes na expressão da relação entre os caracteres. Assim, o melhoramento visando aos caracteres avaliados não precisa ser realizado em ambas as áreas de cultivos orgânico e convencional.

    Full Text Available Objetivo. Conocer los factores psicosociales relacionados con la frecuente rehospitalización de pacientes con psicosis orgánica. Material y métodos. Estudio de tipo observacional descriptivo, de corte transversal. La muestra estuvo formada por 33 pacientes del Hospital Psiquiátrico Guillermo Dávila, con Unidad de Medicina Familiar Número 10 del Instituto Mexicano del Seguro Social de la Ciudad de México, con psicosis orgánica y quienes durante los años de 1993-1994 presentaron más de dos rehospitalizaciones. Instrumentos: Entrevista grabada, o muestra de conversación de cinco minutos, para la emoción expresada (EE, cuestionarios mixtos para la Concepción de Enfermedad y la Relación médico-paciente. La validez y confiabilidad de los datos se establecieron con las pruebas de Kappa y Alpha de Cronbach y se efectuó análisis estadístico descriptivo e inferencial. Resultados. El 60.9% de los familiares presentan alto nivel de EE, es decir, expresan crítica, hostilidad o sobreinvolucramiento emocional; el 64.3% de los sujetos de la muestra conviven más de 35 horas a la semana con familiares que presentan Alta EE. Conclusiones. Altos niveles de EE estuvieron asociados con los frecuentes reingresos a hospitalización. Existe mayor conocimiento de las características de la enfermedad por parte del familiar que del paciente. La relación médico-paciente es satisfactoria pero no forma conciencia de enfermedad ni propicia apego al tratamiento terapeútico.

  12. Org 214007-0: a novel non-steroidal selective glucocorticoid receptor modulator with full anti-inflammatory properties and improved therapeutic index.

    Directory of Open Access Journals (Sweden)

    Marie-José C van Lierop

    Full Text Available Glucocorticoids (GCs such as prednisolone are potent immunosuppressive drugs but suffer from severe adverse effects, including the induction of insulin resistance. Therefore, development of so-called Selective Glucocorticoid Receptor Modulators (SGRM is highly desirable. Here we describe a non-steroidal Glucocorticoid Receptor (GR-selective compound (Org 214007-0 with a binding affinity to GR similar to that of prednisolone. Structural modelling of the GR-Org 214007-0 binding site shows disturbance of the loop between helix 11 and helix 12 of GR, confirmed by partial recruitment of the TIF2-3 peptide. Using various cell lines and primary human cells, we show here that Org 214007-0 acts as a partial GC agonist, since it repressed inflammatory genes and was less effective in induction of metabolic genes. More importantly, in vivo studies in mice indicated that Org 214007-0 retained full efficacy in acute inflammation models as well as in a chronic collagen-induced arthritis (CIA model. Gene expression profiling of muscle tissue derived from arthritic mice showed a partial activity of Org 214007-0 at an equi-efficacious dosage of prednisolone, with an increased ratio in repression versus induction of genes. Finally, in mice Org 214007-0 did not induce elevated fasting glucose nor the shift in glucose/glycogen balance in the liver seen with an equi-efficacious dose of prednisolone. All together, our data demonstrate that Org 214007-0 is a novel SGRMs with an improved therapeutic index compared to prednisolone. This class of SGRMs can contribute to effective anti-inflammatory therapy with a lower risk for metabolic side effects.

    Full Text Available Chromium and its compounds give toxic and/or hazardous characteristics to all those industrial wastes, solids or liquids, that contain them. Organic solvent extraction is a technique that allows the recovery of chromium contained in these residues. In this work the extraction of Cr(III from aqueous solutions with solutions of a cationic reactive (DEHPA in kerosene is studied. In the same way the stripping process was studied. It has been found that Cr(III and DEHPA react in a 1/1 molar ratio, being the extraction kinetics very fast. Final aqueous phase final pH influence extraction yield, so that it is necessary to work with pH values between 3 and 4. It must be added a modifier (isodecanol to the organic phase to avoid the formation of a third phase in the stripping process. The concentration of isodecanol has to be higher than 15 %, so the organic phase used was a solution of 12.5 % v/v DEHPA in kerosene and 20 % v/v isodecanol. The stripping process is slow and must be carried out in an oxidant alkalyne medium, thus an aqueous solution of NaOH and H2O2 was used. An increase in the concentration of NaOH and H2O2 leads to an increase in the stripping yield initially, and becomes stable when concentrations of NaOH and H2O2 used are higher than 0.45 N and 4 % v/v respectively.

    Full Text Available BACKGROUND: Information on polymorphic DNA in organelle genomes is essential for evolutionary and ecological studies. However, it is challenging to perform high-throughput investigations of chloroplast and mitochondrial DNA polymorphisms. In recent years, EcoTILLING stands out as one of the most universal, low-cost, and high-throughput reverse genetic methods, and the identification of natural genetic variants can provide much information about gene function, association mapping and linkage disequilibrium analysis and species evolution. Until now, no report exists on whether this method is applicable to organelle genomes and to what extent it can be used. METHODOLOGY/PRINCIPAL FINDINGS: To address this problem, we adapted the CEL I-based heteroduplex cleavage strategy used in Targeting Induced Local Lesions in Genomes (TILLING for the discovery of nucleotide polymorphisms in organelle genomes. To assess the applicability and accuracy of this technology, designated ORG-EcoTILLING, at different taxonomic levels, we sampled two sets of taxa representing accessions from the Brassicaceae with three chloroplast genes (accD, matK and rbcL and one mitochondrial gene (atp6. The method successfully detected nine, six and one mutation sites in the accD, matK and rbcL genes, respectively, in 96 Brassica accessions. These mutations were confirmed by DNA sequencing, with 100% accuracy at both inter- and intraspecific levels. We also detected 44 putative mutations in accD in 91 accessions from 45 species and 29 genera of seven tribes. Compared with DNA sequencing results, the false negative rate was 36%. However, 17 SNPs detected in atp6 were completely identical to the sequencing results. CONCLUSIONS/SIGNIFICANCE: These results suggest that ORG-EcoTILLING is a powerful and cost-effective alternative method for high-throughput genome-wide assessment of inter- and intraspecific chloroplast and mitochondrial DNA polymorphisms. It will play an important role in

    How can an informal science learning project about climate change facilitate alliances among unlikely parties? We found a sweet spot of collaboration among private, public, and the non-profit sectors by borrowing strength and leveraging common interests. Using mass transit and out of home media, we created a diverse community around a learning campaign that starred an ostrich named "Ozzie." In 2013-14, ScienceToGo.org ran a series of 12 engaging posters and placards staring 'Ozzie the Ostrich' on the Massachusetts Bay Transit Authority's Red and Orange subway lines targeting a daily audience of 400,000+ riders. The curriculum was divided into three phases: reality, relevance, and hope. Phase I established the reality of climate change (3 months). Phase II helped T-riders appreciate the relevancy of climate change to the local environment of Boston (4 months). Phase III engaged Bostonians with an array of hopeful examples of how people, companies, and organizations are effectively creating a more sustainable future (5 months). The focus of this presentation will be on the relationships that emerged from the work that went into Phase III. Engaging urban populations with climate change science is a difficult challenge since cities seem so removed from the 'natural environment.' However, mass transit provides an inherent means of communicating environmental messages with a cross section of the urban population. Our team felt that any messaging curriculum for an urban subway system must complement the scary reality of a changing climate with hopeful solutions that exist for dealing with it effectively. Urban areas such as Boston must develop adaptation and mitigation strategies that will help them not only survive, but thrive in a changing environment. Making our audience aware of the amazing efforts in this area was the goal of Phase III. There were three parts to our efforts: the signage on the subway, above ground ostriches, and social events. During the presentation

    A team of educators, scientists, and communication experts from multiple universities as well as a Science museum will report on the impact of ScienceToGo.org, which is an Out of Home Multi-Media (OHMM) exhibit targeting adults riding a major subway system. The campaign's goal is to design, implement, and study the efficacy of an OHMM model for free choice science learning about our changing climate. Subway riders represent a diverse and captive audience with most of them spending an average of one hour a day in the subway system. Through the use of specially designed OHMM such as train placards, platform posters, and virtual resources the campaign engages a potential audience of 500,000 riders/day with opportunities to learn climate change science informally. The primary goal of the ScienceToGo.org campaign is to engage, entertain, and educate the adult subway riding community in major U.S. city about climate change as a real, relevant, and solvable local challenge. A naturalistic quasi-experimental inquiry employing a mixed methodology approach best describes our research design with half of the subway system exposed to the project signage (experimental group) and the other half not being exposed to the project signage (control group). To identify possible outcomes, data was collected in the several forms: survey, analytic data associated with website, social media, web app, focus groups, and observations. This campaign is an example of how an individual's daily routine may be enhanced with an informal science learning opportunity. We see an urgent need to improve both the public's engagement with climate change science and to the profile of climate change science in formal education settings. The campaign makes deliberate use of humor and fun to engage a public and diverse audience with the serious issue of climate change. The research that will be presented will reveal some of the strengths and weaknesses of this strategy when communicating science to a diverse

    Full Text Available Em solos tropicais, a disponibilidade de fósforo (P pode ser regulada pela decomposição e mineralização da fração lábil de P orgânico (Po, tornando necessários estudos para saber a sua real contribuição no solo. O objetivo deste trabalho foi avaliar o teor de Po total e lábil em horizontes superficiais de diferentes classes de solo e quais as propriedades do solo exercem controle na acumulação dessas frações de P. Foram estudadas amostras de diferentes horizontes diagnósticos superficiais, a saber: H e O hístico; A chernozêmico; e A húmicos, coletados em vários estados do Brasil. Para a determinação das frações totais de P inorgânico (Pi e orgânico (Po, foi usado o método da extração-sequencial ácido-alcalina, e a fração lábil de P foi determinada pela extração com bicarbonato de sódio. A taxa de recuperação de Pi + Po em relação à extração nítrico-perclórica do P total (PT variou de 46 a 99 %. O Po total variou entre 35 e 1077 mg kg-1, com uma média de 298 mg kg-1. Para a fração lábil do Po, os teores variaram entre 7,2 e 99,5 mg kg-1, com uma média de 27,1 mg kg-1. O Po variou, em média, de 36 a 46 % do P total extraído. Em relação ao P lábil, o Po representou mais de 70 % para todos os horizontes diagnósticos. O PT foi o principal atributo controlador da acumulação de Po nos solos pelas análises de correlação e regressão múltipla. Verificou-se que horizontes com baixa capacidade de adsorção de P proporcionaram alta labilidade de Po.

Se realizaron ensayos de resistencia triaxial sobre probetas de suelo orgánico, natural y estabilizado. El tratamiento se materializó incorporando al suelo resinas en las que intervinieron productos obtenidos de la cadena de fabricación del tanino de Quebracho Colorado, un aldehído y agua. La concentración de la resina fue variable, como también la proporción con respecto al peso seco del suelo en que se la agregaba y los días de curado. Los ensayos triaxiales permitieron el trazado de las líneas de resistencia intrínseca para evaluar la acción del estabilizante. Los resultados indicaron un incremento en la resistencia mecánica del suelo estabilizado, pudiéndose identificar la resina que indujo a un mejor efecto sobre el suelo natural, permitiendo extender las posibilidades de aplicación del material tratado.The aim of this work was evaluating the strength of organic soils in northeastern region of Argentina after completing the stabilization process with different types of resins. Several triaxial essays on probes of organic, natural and stabilized soils, were carried out.

    On March 17, 2015, a geomagnetic storm—the largest of the solar cycle to date— hit Earth and gave many sky watchers around the world a beautiful auroral display. People made thousands of aurora-related tweets and direct reports to Aurorasaurus.org, an interdisciplinary citizen science project that tracks auroras worldwide in real-time through social media and the project's apps and website. Through Aurorasaurus, researchers are converting these crowdsourced observations into valuable data points to help improve models of where aurora can be seen. In this presentation, we will highlight how the team communicates with the public during these global, sporadic events to help drive and retain participation for Aurorasaurus. We will highlight some of the co-produced scientific results and increased media interest following this event. Aurorasaurus uses mobile apps, blogging, and a volunteer scientist network to reach out to aurora enthusiasts to engage in the project. Real-time tweets are voted on by other users to verify their accuracy and are pinned on a map located on aurorasaurus.org to help show the instantaneous, global auroral visibility. Since the project launched in October 2014, hundreds of users have documented the two largest geomagnetic storms of this solar cycle. In some cases, like for the St. Patrick's Day storm, users even reported seeing aurora in areas different than aurora models suggested. Online analytics indicate these events drive users to our page and many also share images with various interest groups on social media. While citizen scientists provide observations, Aurorasaurus gives back by providing tools to help the public see and understand the aurora. When people verify auroral sightings in a specific area, the project sends out alerts to nearby users of possible auroral visibility. Aurorasaurus team members around the world also help the public understand the intricacies of space weather and aurora science through blog articles

    This study utilizes zircon SIMS U-Pb dating, REE and trace-element analysis as well as oxygen isotope ratios of zircon to distinguish jadeite-rich rocks that formed by direct crystallization from a hydrous fluid from those that represent products of a metasomatic replacement process. Zircon was separated from a concordant jadeitite layer and its blueschist host, as well as from loose blocks of albite-jadeite rock and jadeitite that were all collected from the Jagua Clara serpentinite-matrix mélange in the northern Dominican Republic. In the concordant jadeitite layer, three groups of zircon domains were distinguished based on both age as well as geochemical and oxygen isotope values: age groups old (117.1 ± 0.9 Ma), intermediate (three dates: 90.6, 97.3, 106.0 Ma) and young (77.6 ± 1.3 Ma). Zircon populations from the blueschist host as well as the other three jadeite-rich samples generally match zircon domains of the old age group in age as well as geochemistry and oxygen isotope ratios. Moreover, these older zircon populations are indistinguishable from zircon typical of igneous oceanic crust and hence are probably inherited from igneous protoliths of the jadeite-rich rocks. Therefore, the results suggest that all investigated jadeite-rich rocks were formed by a metasomatic replacement process. The younger domains might signal actual ages of jadeitite formation, but there is no unequivocal proof for coeval zircon-jadeite growth.

    At the NW of the Iberian Variscan Massif the Parautochthon is envisaged as an intervening structural unit located between the far-traveled allochthonous stacked units and the autochthon. It has been recently divided in two structural slices; the Upper constitutes a repetition of the upper Cambrian to Silurian sequence of the Central Iberian Zone autochthon, while the Lower has been proposed as a thick Variscan synorogenic deposit. A large volcanic block embedded in the uppermost Devonian-lower Carboniferous Lower Parautochthon yields an U/Pb age of 497 ± 2 Ma (upper Cambrian). This age, joined to the petrographic features and the chemical composition, supports the provenance area for the large glided block in the Upper Parautochthon, where a magmatic event of similar age and characteristics has been identified. This source area for the slid block reinforces the idea of a mélange developed in the synorogenic trough at the front of a main thrust structure, which over thrusts the Upper Parautochthon on top of the Lower Parautochthon.

    Uno de los mayores problemas de la fertilidad de los suelos de los Llanos Orientales, en la Orinoquia colombiana, es la alta fijación del fósforo ocasionada principalmente por los compuestos presentes en su fracción arcilla. El uso de mezclas de materiales orgánicos y minerales puede ayudar a disminuir esta fijación, para lo que se utilizaron dos materiales orgánicos –gallinaza y compost– y dos materiales inorgánicos –cal y superfosfato triple (SPT)– y se estableció un total de 13 tratamiento...

    2014-12-01

    A significant number of U.S. citizens have real concerns that actions to curb climate change threaten prosperity and basic freedoms and present an affront to their own values. Others are so worried that climate change will destroy Earth's environment and any prospects for their descendants that they are either frantic to find solutions, or too discouraged to act. To attempt to reach these disparate audiences with critical scientific information from reports such as the IPCC and NCA, the University Corporation for Atmospheric Research and the United Nations Foundation initiated the Scientist Citizen Initiative, and launched Climate Voices - Science Speakers Network (climatevoices.org) in April of this year. This presentation will address the trials and errors of establishing such a network, engaging scientists across the country, and creating public demand for such a resource. The major focus will be lessons still being learned about reaching diverse local audiences; gauging and implementing the varied approach necessary to engage such audiences; and enabling scientists to initiate public conversations involving fellow citizens in discussion of climate change observations, impacts, and solutions. How can partners be identified and involved that deliver mixed audiences ranging from the Six Americas' "alarmed and concerned" to the "doubtful and dismissive?" [Yale Project on Climate Communication] How can synthesis report results be made compelling and relevant to such audiences? How can such an effort be implemented across the entire country? How can its accomplishments and failures be assessed and evaluated? This presentation will provide answers in progress to these questions.

    communities of fungi and bacteria in the phylloplane, and to the occurrence of weeds.Diversos sistemas agrícolas alternativos têm sido desenvolvidos e, dentre eles, a agricultura orgânica tem recebido destaque, despertando interesse por parte dos agricultores. Compararam-se o sistema orgânico (SO e o convencional (SC de tomates da variedade Débora e Santa Clara, por meio de um estudo interdisciplinar. O experimento foi conduzido em blocos casualizados com seis repetições, com parcelas medindo 25 ´ 17 m, em um Argissolo Vermelho-Amarelo distrófico. Todas as práticas culturais foram realizadas de acordo com as técnicas utilizadas pelos agricultores convencionais ou orgânicos da região. No SO a fertilização foi realizada aplicando, em cada cova, composto orgânico, superfosfato simples e calcário dolomítico (5 L, 60 g e 60 g e pulverizando biofertilizante duas vezes por semana. No SC, foi utilizado 200 g 4-14-8 (NPK por cova e, após o plantio, 30 g N, 33 g K and 10,5 g P por cova; a partir de 52 dias após o plantio, as plantas foram pulverizadas com adubo foliar uma vez por semana. No SC, para o controle dos problemas fitossanitários, foram realizadas aplicações de mistura de inseticidas, fungicidas e acaricidas duas vezes por semana. Para o SO o controle foi realizado pulverizando-se extratos de pimenta-do-reino, de alho e de eucalipto; calda bordaleza e biofertilizante duas vezes por semana. O vira-cabeça foi a principal doença do SO, resultando em menor desenvolvimento de plantas, número de inflorescência e produção. No SC, a doença foi mantida sob controle, sendo que a população de tripes, vetor do vírus, ocorreu em níveis inferiores que no SO. A variedade Santa Clara apresentou maior incidência da virose e, por esse motivo, teve desempenho inferior à Débora, especialmente no SO. A ocorrência de Liriomysa spp. foi significativamente menor no SO, possivelmente devido à maior freqüência de Chrysoperla. O SC apresentou menor incid

    Full Text Available Weed control has always been an important issue in agriculture. With the advent of no-till systems, soil erosion was reduced but herbicide use was increased. Organic no-till systems try to adjust reduced erosion to the no use of herbicides. Nevertheless, this adjustment is limited by the cost of mechanical weed control. This cost may be reduced by improved cultural weed control with cover crops mulches. In this paper we report a study on the application of compost manure on an oats winter cover crop, preceding soybean, instead of on the soybean summer crop. Treatments comprised a control without compost manure, and compost manure doses of 4 and 8 Mg ha-1 applied either on oats in winter or soybean in summer, organized in a randomized block design, with five replications. In summer, plots were split into weed-controlled or not controlled subplots. The timing of application and the manure doses did not affect the oats biomass or the soybean performance. However, in summer, without water stress, the application of manure at 8 Mg ha-1 directly on soybean has reduced weed biomass in this crop.O controle de plantas daninhas sempre foi um fator importante na agricultura. Com o advento do plantio direto reduziu-se a erosão do solo, mas houve aumento no uso de herbicidas. O plantio direto orgânico busca conciliar o controle da erosão com a eliminação do uso de herbicidas, porém o custo de produção é onerado pela necessidade de controle mecânico das plantas daninhas. Esse custo poderia ser reduzido por um melhor controle cultural com palhas produzidas por plantas de cobertura no inverno. Neste trabalho, antecipou-se a adubação da soja para a aveia, aplicando na aveia o adubo que seria aplicado na soja, de modo a aumentar a quantidade de palha de aveia sobre a qual a soja seria semeada no verão seguinte. O delineamento experimental foi em blocos ao acaso com parcelas subdivididas. Os tratamentos foram uma testemunha sem adubação e duas doses

    The radiosynthesis of [N-methyl-{sup 11}C]Org 34850 as a potential brain glucocorticoid receptor (GR)-binding radiotracer is described. The radiosynthesis was accomplished via N-methylation of the corresponding desmethyl precursor with [{sup 11}C]methyl triflate in a remotely controlled synthesis module to give the desired compound in a radiochemical yield of 23{+-}5% (decay-corrected, based upon [{sup 11}C]CO{sub 2}) at a specific activity of 47{+-}12 GBq/{mu}mol (n=15) at the end-of-synthesis (EOS). The radiochemical purity after semi-preparative HPLC purification exceeded 95%. The total synthesis time was 35-40 min after end-of-bombardment (EOB). The radiotracer is rapidly metabolized in rat plasma leading to the formation of two more hydrophilic metabolites as the major metabolites. Radiopharmacological evaluation involving biodistribution and small animal PET imaging in normal Wistar rats showed that the compound [N-methyl-{sup 11}C]Org 34850 is not able to sufficiently penetrate the blood-brain barrier. Therefore, compound [N-methyl-{sup 11}C]Org 34850 seems not to be a suitable PET radiotracer for imaging rat brain GRs. However, involvement of Pgp or species differences requires further clarification to establish whether the radiotracer [N-methyl-{sup 11}C]Org 34850 may still represent a suitable candidate for imaging GRs in humans.

    Full Text Available Discutiram-se os critérios de avaliação de materiais orgânicos empregados como fertilizantes adotados na legislação brasileira atual. Trabalhando com amostras de compostos, estéreos, resíduos industriais e turfa, discutiu-se a determinação de carbono orgânico através de oxidação pelo íon dicromato. Sugeriu-se que o atual método de determinação de matéria orgânica total por combustão tenha sua utilização restrita ou desaconselhada, devido aos erros grosseiros que proporciona. Como forma de se avaliar a qualidade de materiais orgânicos, discutiu-se a determinação da capacidade de retenção de cátions (CTC em fertilizantes e materiais orgânicos em geral. O grau de maturação ou estabilidade de compostos orgânicos pôde ser convenientemente expresso através da relação entre CTC (meq/l00g e o teor de carbono orgânico expresso em porcentagem.The present paper aimed to study the determination of organic carbon and the cation exchange capacity (CEC of organic materials which can be used as fertilizers. Analytical procedures recommended by Brazilian official methods of fertilizer analysis include the determination of total organic matter by incineration. The errors of this method are not taken into account in spite of the great variability of the organic materials. This paper suggests that the organic characteristics of organic fertilizers must be expressed by the organic carbon content as determined by wet oxidation with dichromate ion and sulfuric acid. There is a great demand for practical indexes for determining the state of composting since the incorporation into the soil of immature organic material can cause severe damage to crops. In order to evaluate the maturity of organic products as manures, compost industrial wastes and peat, the determination of CEC was discussed. It seems possible to define the chemical stabilization of organic materials on the basis of the relationship between CEC and organic carbon

    Full Text Available Los compuestos orgánicos fluorados (FOCs o productos químicos perfluorados constituyen un grupo de sustancias utilizadas ampliamente a nivel industrial. El sulfonato de perfluorooctano (PFOS pertenece a este grupo de compuestos y es además el producto de degradación de numerosos FOCs. Este xenobiótico es extremadamente persistente en el medioambiente. Para la población general, las principales vías de exposición a PFOS son: la ingesta alimentaria, la vía inhalatoria y el contacto dérmico. El PFOS se absorbe principalmente por vía oral, se transporta en sangre unido a la albúmina, es capaz de atravesar la placenta y la barrera hematoencefálica y se elimina por vía renal. El principal órgano diana del PFOS es el hígado. Además de los efectos hepatotóxicos y metabólicos observados tras la exposición a este xenobiótico, también están involucrados en sus mecanismos de acción tóxica diversos receptores como son los activadores de proliferación de peroxisomas o PPAR. Al mismo tiempo, presenta inmunotoxicidad, alterando la secreción de citoquinas, la diferenciación celular de monocitos, linfocitos, etc. así como la actividad de las células natural killer. Además, el PFOS es neurotóxico, tanto a nivel central como periférico, e induce importantes alteraciones neuroendocrinológicas en distintos órganos y tejidos que constituyen los ejes hipotalámico-hipofisario-gonadal e hipotalámico-hipofisario-adrenal.

    In the central-northern margin of the North China Craton, the tectonic boundary between the Jining and Huai'an Complexes is well exposed in the Gushan area. In this boundary zone, exotic blocks of orthopyroxene-bearing monzonitic gneiss, garnet-bearing mafic granulite, marble, and calc-silicate were identified in the meta-psammitic and meta-pelitic matrix. The likely nature of the rock units is a tectonic mélange, which is a key to understand the tectonic evolution of the craton. In this paper, geochronological and geochemical studies have been carried out on representative lithologies from the Gushan area to discuss their petrogenesis and geodynamic settings. The opx-bearing monzonitic gneisses (U-Pb zircon emplacement age of 2.17 Ga) are high-K calc-alkaline to shoshonitic I-type rocks with trace-element magmatic arc signature. The trace elements, whole rock Sm-Nd and zircon Lu-Hf isotopes suggest that they were possibly derived from partial melting of Neoarchean lower crust (garnet amphibolite) in a continental arc. The protoliths of the garnet-bearing mafic granulites are inferred to have formed between 2.37 Ga and 1.95 Ga, possibly at 2.2 Ga. They show N-MORB geochemical affinity and were most likely produced by partial melting of spinel lherzolite in a mid-ocean ridge setting. Detrital zircons from one metapsammite sample (garnet-bearing quartzofeldspathic gneiss) yield nearly concordant 207Pb/206Pb ages ranging from 2.1 Ga to 2.0 Ga. In situ U-Pb and Hf isotopic data of zircons from the metapsammite sample support that the metasedimentary protoliths were probably derived from a mid-Paleoproterozoic continental arc. Three metamorphic age groups (1.95-1.93 Ga, 1.86-1.83 Ga, and 1.80 Ga) are revealed by the opx-bearing monzonitic gneisses, garnet-bearing mafic granulites, garnet-bearing quartzofeldspathic gneiss, and sillimanite-garnet-K-feldspar gneiss. The predominant group (1.95-1.93 Ga) is considered to record the age of near-peak granulite facies

    Full Text Available On décrit un nouveau brûleur compact à gaz, de haut rendement et d'une puissance variable de 1 à 5 kW. La source de chaleur est une flamme plate d'un prémélange stoechiométrique de gaz naturel et d'air stabilisé sur une grille d'une surface de 100 cm2. Plusieurs grilles en acier inoxydable sont comparées. Elles diffèrent par leur épaisseur, le nombre et la dimension des trous. Un échangeur de chaleur en laiton à circulation d'eau peut être approché jusqu'à 7 mm de la surface du brûleur. La température des gaz frais, le débit et la position de l'échangeur ont été modifiés et les conditions optimales de fonctionnement sont décrites. Les températures à travers les gaz frais, la flamme, les gaz brûlés et les fumées, ont été mesurées. Un modèle simple des échanges de chaleurs est présenté. Il permet une meilleure compréhension des processus de transfert et facilite le choix des conditions opératoires. Dans les meilleures conditions, 93 % du contenu thermique du mélange gazeux est transféré à l'échangeur. Some general characteristics of a compact and efficient gas burner are described (1-5 kW. The heat source is a premixed flat flame stabilized on a 100 cm2 grid fed by a stoechiometric mixture of air and natural gas. Various types of stainless steel grids have been investigated. They differ according to their thickness and to the number and size of the holes. A circulating water heat exchanger made of brass can be approached to the flame as close as 7 mm above the burner surface. The temperature of the inlet gas mixture, the flow rate, and the position of the heat exchanger have been varied. The best working conditions are given as well as the temperature through the fresh gaseous mixture, the temperature profiles of the flame and the temperature of the fumes. From heat transfer calculations a simple model is presented. It gives better insight into the heat transfer processes and facilitates a judicious

    Full Text Available Abstract Background Intellectual disability (ID is a devastating and frequent condition, affecting 2-3% of the population worldwide. Early recognition of treatable underlying conditions drastically improves health outcomes and decreases burdens to patients, families and society. Our systematic literature review identified 81 such inborn errors of metabolism, which present with ID as a prominent feature and are amenable to causal therapy. The WebAPP translates this knowledge of rare diseases into a diagnostic tool and information portal. Methods & results Freely available as a WebAPP via http://www.treatable-id.org and end 2012 via the APP store, this diagnostic tool is designed for all specialists evaluating children with global delay / ID and laboratory scientists. Information on the 81 diseases is presented in different ways with search functions: 15 biochemical categories, neurologic and non-neurologic signs & symptoms, diagnostic investigations (metabolic screening tests in blood and urine identify 65% of all IEM, therapies & effects on primary (IQ/developmental quotient and secondary outcomes, and available evidence For each rare condition a ‘disease page’ serves as an information portal with online access to specific genetics, biochemistry, phenotype, diagnostic tests and therapeutic options. As new knowledge and evidence is gained from expert input and PubMed searches this tool will be continually updated. The WebAPP is an integral part of a protocol prioritizing treatability in the work-up of every child with global delay / ID. A 3-year funded study will enable an evaluation of its effectiveness. Conclusions For rare diseases, a field for which financial and scientific resources are particularly scarce, knowledge translation challenges are abundant. With this WebAPP technology is capitalized to raise awareness for rare treatable diseases and their common presenting clinical feature of ID, with the potential to improve health outcomes

    The general use of pesticides in the Orge Basin, located in the southern part of the Paris suburb (France), is damaging surface water quality. Consequently, an increase in the water supply costs is registered by the water supply agencies that are situated downstream the Orge confluence with the Seine River. In this catchment, high uses of glyphosate are registered for fallow fields (upstream part) and for roadway weed control (downstream part). The proportion of glyphosate coming from these two zones was not well known, along with the double source of its metabolite AMPA originated from the degradation of some detergent phosphonates. The aim of this work was firstly to identify the potential sources of glyphosate and AMPA in urban sectors (such as sewerage system inputs) and in agricultural areas and to quantify the origins of urban pesticides pathways towards surface waters at the basin scale. The new approach of this project was to collect information at three different scales to establish a first step of modeling. At the basin scale, 1 year of surface water monitoring at the outlet of the Orge River was useful to establish the inputs towards the Seine River. At the urban catchment scale, the investigations have permitted to record glyphosate and AMPA loads transferred by storm waters and by wastewaters. Loads were estimated during and out of application calendar, in different hydrological conditions such as rainfall with high intensity or dry conditions. Impact of WWTP on surface water was also demonstrated. The third phase of this work was the interpretation of agricultural inputs from two different agricultural catchments of the Orge River. The results showed the impact of urban uses of glyphosate upon the Orge River contamination with annual loads from 100 times higher from the urban zone than from the agricultural one. Storm sewers were recognized to be the main way for glyphosate transfer towards surface waters. A budget of glyphosate and AMPA inputs and

  15. Synthesis and organ distribution of [18F]Fluoro-Org 6141 in the rat: A potential glucocorticoid receptor ligand for positron emission tomography

    International Nuclear Information System (INIS)

    For the synthesis of [18F]Fluoro-Org 6141 via a nucleophilic substitution reaction with 18F-, the tosyl group was chosen as the leaving group because of its stability and excellent leaving group ability. The biodistribution of the high affinity and moderate lipophilicity (log P 2.66, calculated value) ligand [18F]Fluoro-Org 6141 (specific activity 8.2 to 37 TBq/mmol, yield 10% at EOB) was examined in sham adrenalectomized (sADX) and adrenalectomized (ADX) male Wistar rats. Two days after ADX or sADX, the animals were anesthetized and 0.37 to 1.85 MBq of [18F]Fluoro-Org 6141 was administered intravenously. Kinetics of 18F activity uptake were monitored for 3 h using a stationary double-headed positron emission tomography (PET) camera, and the biodistribution was assessed by ex vivo determination of radioactivity in several tissues and different brain areas. One hour after injection of the radioligand, the bladder, kidney, liver, trachea, and bone of sADX animals contained more concentration on a wet weight basis than blood. Three hours post injection, radioactivity was retained in bladder, trachea, and bone. The accumulation of radioactivity in brain corresponded to the concentration of activity in the blood within the first hours after injection. ADX animals showed a higher uptake of 18F activity in spleen, testes, and brain areas (hippocampus and brainstem) but a lower uptake in bone than sADX rats. PET scans suggested that 18F activity uptake in the brain had not yet reached a maximum at this interval. Although [18F]Fluoro-Org 6141 is not useful for PET studies of glucocorticoid receptors (GRs), the results obtained with this compound indicate a synthetic strategy suitable for the synthesis of high-affinity radioligands for GRs

    Full Text Available The purpose of this article is to show a more accurate orifice equation for a two-phase flow, such a compressible mixture of gas and liquid. The orifice equation given here con be used for the measurement of a gas-liquid mixture of fine emulsions by the orificemeter method. From the thermodynamic point of view, an equation of state has been formulated which provides the relationship between the specific mass of the mixture and pressure, under conditions of adiabatic expansion. The results obtained enable the mass flow rates of gas and liquid ta be determined without separation of the phases, provided thot the gas liquid mass ratio is known. The critical pressure ratio corresponding ta sonic velocity is also determined. Cet article présente une relation plus précise pour l'écoulement d'un système à deux phases, tel qu'un mélange compressible gaz-liquide, à travers un diaphragme. Cette relation peut être utilisée pour des mesures de mélanges gaz-liquide très finement divisés, c'est-à-dire des émulsions ou brouillards, par la méthode du diaphragme en paroi mince. Du point de vue thermodynamique, on a formulé une équation d'état donnant la relation entre la masse spécifique du mélange et la pression dans des conditions d'expansion adiabatique. Les résultats obtenus per-mettent de déterminer le débit massique du gaz et du liquide, sans séparation des deux phases, à condition que le rapport de masse gaz-liquide soit connu. On détermine également le rapport de pression critique correspondantà la vitesse du son.

    Full Text Available A taxa de mineralização do nitrogênio (N varia de um resíduo orgânico para outro, evidenciando-se dependente da sua composição química e interação do material orgânico com o solo. Este estudo foi realizado com o objetivo de avaliar a dinâmica de mineralização de N de resíduos orgânicos incubados em Latossolos. O experimento foi conduzido no período de julho de 2007 a abril de 2008, sendo incubadas amostras de estercos, lodos, compostos, substrato e turfa em areia lavada, Latossolo Vermelho-Amarelo (LVA e Latossolo Vermelho distroférrico (LVdf, com 240 e 670 g kg-1 de argila, respectivamente. O N mineralizado foi avaliado medindo-se os teores de N-NH4+ e N-NO3- em lixiviados coletados aos 15, 30, 45, 60, 75, 90, 120, 150, 180, 210, 240 e 270 dias de incubação. A mineralização de N ocorreu a maiores taxas nos períodos iniciais de incubação. O N mineralizado (33 a 199,2 mg kg-1 após 270 dias de incubação é regulado pelos teores de N total e de carbono solúvel em água dos resíduos orgânicos. Independentemente do meio utilizado para incubação, os estercos de galinha e de codorna propiciaram os maiores teores de N mineralizado nos Latossolos. À exceção dos estercos de galinha e codorna, há imobilização líquida de N no LVA; mineralização líquida de N é verificada no LVdf, para todos os resíduos orgânicos. Em relação às formas de N disponibilizadas pelos resíduos, predomina o N-nitrato, sendo a proporção N-nítrico/N-amoniacal dependente da mistura solo-resíduo estudada.

    The Yikehalaer intrusives are distributed in the Buqingshan tectonic mélange belt at the southern margin of East Kunlun, China. They tectonically intruded the conglomerate of Permian Gequ Formation to the south and the marble of Mesoproterozoic Kuhai Group to the north. These intrusives mainly consist of off-white coarse- and fine-grained granodiorite and granite. U-Pb dating of zircons from the intrusive samples yielded weighted mean 206Pb/238U ages of 436 ± 7 Ma and 437 ± 6 Ma, indicating Early Silurian crystallization age. The intrusives are high-silica, Na-rich, I-type calc-alkalic rocks. They are divisible into two subgroups on the basis of their trace element content: adakitic rocks in the northern part and normal calc-alkalic arc rocks in the southern part. Rocks in the northern part exhibit high Sr (280-493 ppm), low Y (3.8-11.7 ppm), high Sr/Y ratios (23.9-125.0), high light rare earth elements (LREE)/ heavy rare earth elements (HREE) (15.1-35.7), and invisible Eu/Eu∗. They resemble adakites formed by slab melting in subduction zones. However, the rocks in the southern part possess the attributes of normal arc rocks. In addition, the εHf(t) values of the intrusives are consistently positive (0.6-7.6), implying that they were generated by melting of an isotopically depleted mantle source, with insignificant contributions from crustal materials. The source residues likely contained 10-20% garnet and hornblende, and plagioclase was either absent or totally consumed during partial melting. Combining the regional tectonic data, we conclude that the Buqingshan paleo-ocean may have started to subduct in Middle Cambrian until Early Silurian (436 Ma), generating an important adakitic magma event during the late stage of oceanic crust subduction. Moreover, the Proto-Tethyan Ocean closed, and the Bayan Har, East Kunlun, and Qaidam blocks collided during the Middle-Late Silurian.

La vérification théorique et expérimentale de ce principe ainsi que ses limites d'application comme moyen de mesure sont présentées. Ce résultat a été utilisé pour développer un système de mesure de l'aération de l'huile moteur, le SMAC (Système de Mesure d'Aération par Compressibilité. Des exemples d'application, tels que l'étude de la sensibilité de certaines huiles à l'aération, sont exposés. Oil aeration can be a real problem in engine oil circuit. The involved lubrication power decrease and thermic properties changes can damage the engine. Furthermore, the increased compressibility is very dangerous for hydraulic systems like valve lash adjusters. A first step to control this aeration is to be able to measure it. Gammametry is often used but this measurement needs a very precise calibration and is quite complicated and dangerous. A new absolute measurement has been discovered, based on the difference of compressibility between air and oil. It is absolute because the measurement principle is independant of the conditions, The system does not need a new calibration at each new environment. It is valid for any gas-liquid mixture. From the (P, V graph of a gas-liquid mixture compression, one can derive the gas-liquid volumetric ratio. The log-log graph (P/PO, 1-V/VO of a mixture sample pressurization always shows an inflexion point. The y value of this inflexion point (1-V/VO is equal to the volumetric gas ratio of the sample (before compression. This phenomenon is obvious on hydraulic curves (see Annexe 1. To check it, we have proceeded to a theoretical demonstration and an experimental verification. The theoretical demonstration of this principle concludes that the principle is verified as long as the ration P index 0 / alpha B is small. B is the oil bulk modulus, alpha is the volumetric gas ratio

    Full Text Available With the rise of China's status on international stage as a result of its economic development there is an increasingly audible voice of Chinese cultural nationalism. More and more educators and intellectuals are calling for the revival of Chinese traditional culture values. However, the very issues of who are the Chinese and what are traditional Chinese cultural values present a huge dilemma. The debates on a recent a TV program "General Shi Lang" consist a good case to illustrate this dilemma. Shi Lang was a general of the last days of the Ming Dynasty, but had surrendered to the Manchu Qing dynasty invaders and fought for the Machus take over Taiwan from a Chinese ruler. The debates show that the dilemma has its cause in at least three issues. First, it is not at all obvious who should be categorized as Chinese. Secondly, it is not at all obvious what Chinese cultural values are. And finally it is the issue of evaluation of traditional values against the universal claim of the values of liberal democracy.

Laminated microbial mats from a hypersaline lagoon (Guerrero Negro, Baja California, Mexico) maintained in a flume in a greenhouse at NASA Ames Research Center were sampled for δ(13) C of organic material and carbonate to assess the impact of carbon fixation (e.g., photosynthesis) and decomposition (e.g., bacterial respiration) on δ(13) C signatures. In the photic zone, the δ(13) C org signature records a complex relationship between the activities of cyanobacteria under variable conditions of CO2 limitation with a significant contribution from green sulfur bacteria using the reductive TCA cycle for carbon fixation. Carbonate is present in some layers of the mat, associated with high concentrations of bacteriochlorophyll e (characteristic of green sulfur bacteria) and exhibits δ(13) C signatures similar to DIC in the overlying water column (-2.0‰), with small but variable decreases consistent with localized heterotrophic activity from sulfate-reducing bacteria (SRB). Model results indicate respiration rates in the upper 12 mm of the mat alter in situ pH and HCO3- concentrations to create both phototrophic CO2 limitation and carbonate supersaturation, leading to local precipitation of carbonate minerals. The measured activity of SRB with depth suggests they variably contribute to decomposition in the mat dependent on organic substrate concentrations. Millimeter-scale variability in the δ(13) C org signature beneath the photic zone in the mat is a result of shifting dominance between cyanobacteria and green sulfur bacteria with the aggregate signature overprinted by heterotrophic reworking by SRB and methanogens. These observations highlight the impact of sedimentary microbial processes on δ(13) C org signatures; these processes need to be considered when attempting to relate

    Full Text Available Objetivou-se, neste trabalho, avaliar os efeitos da cobertura do solo e da adubação orgânica sobre a temperatura e a umidade do solo, a incidência de plantas daninhas e a produtividade da alface. O delineamento experimental utilizado foi de blocos casualizados, em esquema fatorial (3 x 3, em que o primeiro fator corresponde aos tipos de cobertura morta (capim tifton, capim napier e ausência de cobertura e, o segundo, aos adubos (esterco bovino, esterco de galinhas e ausência de adubação. Analisaram-se as variáveis temperatura e umidade do solo, o número de folhas produzidas pela alface, as massas de matéria fresca e seca da parte aérea, das plantas de alface e daninhas, e o levantamento fitossociológico das plantas infestantes. As plantas adubadas com esterco de galinhas apresentaram massas de matéria fresca e seca superiores às das plantas não adubadas. A cobertura morta com capim tifton proporcionou aumento da massa de matéria seca das plantas de alface, o que pode estar relacionado com a menor temperatura dos canteiros que receberam esse material como cobertura. Commelina benghalensis foi a planta infestante mais importante no cultivo orgânico de alface. A aplicação de adubos orgânicos e a cobertura morta com capins não foram capazes de suprimir plantas daninhas e manter a umidade do solo, em áreas de cultivo de alface.

    Full Text Available Este trabalho teve como objetivo comparar a adaptabilidade e estabilidade de cultivares de café quanto à média de produtividade anual e de biênios, pelo método de EBERHART & RUSSEL (1996, e selecionar cultivares de café para o cultivo orgânico em Minas Gerais. Os experimentos foram conduzidos em três locais, em delineamento de blocos casualizados com trinta genótipos e três repetições. Uma análise se baseou na produtividade média anual de quatro colheitas (2005/2006, 2006/2007, 2007/2008 e 2008/2009 com o total de doze ambientes. A outra análise considerou a média de dois biênios (2005/2006 e 2006/2007; 2007/2008 e 2008/2009 com o total de seis ambientes. A análise em que se considerou a média da produtividade do biênio apresentou redução expressiva do coeficiente de variação ambiental. Por isso, foi possível identificar mais cultivares com adaptabilidade e estabilidade para o cultivo orgânico. Conclui-se que a análise de adaptabilidade e estabilidade com base na produtividade de biênio é mais segura para a seleção de cultivares. Considerando essa premissa, as cultivares 'Catucaí Vermelho 36/6', 'Catuaí Vermelho IAC 15' e 'Siriema 842' são indicadas somente para os ambientes favoráveis. As cultivares 'Sabiá 708', 'IBC Palma 1', 'Catucaí Amarelo 24/137', 'Oeiras MG 6851' e as linhagens H518 e H514 são indicadas para o cultivo orgânico em locais com ambientes similares aos avaliados em Minas Gerais.

    Thadia Turon Silva

    2005-04-01

    Full Text Available O objetivo deste trabalho foi avaliar a utilização da microfiltração para obtenção de suco de maracujá orgânico clarificado e sua aceitabilidade sensorial. O maracujá foi cultivado sob sistema orgânico, em pomares localizados no Estado do Rio de Janeiro. O suco foi submetido a um tratamento enzimático antes da microfiltração, realizada em membranas tubulares com tamanho de poro médio de 0,3 mm e área de filtração de 0,05 m², com o fim de diminuir a viscosidade do suco e, conseqüentemente, melhorar a eficiência do processo. O processo promoveu a completa remoção dos sólidos em suspensão no suco permeado, o que resultou em um suco límpido e clarificado. O refresco de maracujá, obtido a partir do suco de maracujá orgânico microfiltrado, obteve boa aceitabilidade sensorial, tendo sido aprovado por 75% dos consumidores. Foi possível conservar o suco armazenado em embalagens de plástico durante 28 dias, sob refrigeração a 7ºC. Este estudo confirma a eficiência da microfiltração como método alternativo de conservação de suco de maracujá e evidencia a importância dessa técnica no processamento de sucos orgânicos.The objective of this work was to evaluate the use of microfiltration to obtain clarified organic passion fruit juice and analyse its sensory acceptability. Passion fruit was cultivated under organic system in Rio de Janeiro State. The juice was submitted to an enzymatic treatment before microfiltration, in order to decrease its viscosity and pulp content, and to improve permeate flux.
